Category 4 is a monthly broadcast concept from Michael Brunner [ @four4 ] for Great Circles Radio.

Each episode is broken into four segments, which are connected in some fashion, but routinely unique in many others. This allows for the drawing of comparisons between otherwise disparate concepts, while simultaneously creating enough creative restrictions to focus the musical selections.

The 15th episode comes to us courtesy of Grant Aaron (@insideout), founder of Mysteries of the Deep (@mysteriesofthedeep).

We invite our listeners to guess these categories during the show.
As an added incentive for participation, the first person to guess the categories during the broadcast will be eligible to win a prize. Each month brings new categories and prizes.

The theme for episode 15 was -- Fax, Phase I-IV.

Category 4 w/ Grant Aaron - Episode 15: Fax, Phase I-IV

It is undeniable that we are living in uncertain times. For those of us failing to fit the patriarchal neoliberalist mould, we have lost hope in the future. We can see capitalism is not working but we cannot yet envisage an alternative. In a world where security is no longer feasible, the only constant we can rely on is change. Regardless of one’s point of reference, we can understand that every aspect of life, physical and mental is in flux and perhaps this transience is the only thing we can depend on.

This month we have invited @claradeasis to ruminate on these ideas and create an hour of relief from these (and other) anxieties. Clara is a composer and performer of contemporary experimental music. She develops an approach to sound that highlights simplicity, non-intervention and active listening as means of music making. Her works display an extreme precision and intuitive openness that involves a dedicated attention to sound on its details and its most pure forms. 
For this episode of Transience, Lou had the pleasure of hosting Clara at their home studio where they recorded the piece live.

transience #39 with Lou Drago

"A journey to a complementary universe, beyond physical laws and everything that is considered ordinary. It is in this unknown place where the limit is set by your own imagination and where this marvellous exquisite corpse is born."

"A thriller; ear-trained to sound waves that integrate many more textures than a purely conventional sound. An integral of sounds that takes you to a much wider dimension. A cleverly executed action to create a tension sought to achieve a desired end."

HOCast #98 - s.soo

Everyone at some point in their existence experiences a critical moment in their busy life where big decisions can lead to big change, both at work and in life. A turning point that make your life never be the same again. A new you, a new us.

David is a die-hard record collector who has been playing them around the North of Spain and Europe for more than 15 years now. Since three years ago he's more focused on Escala de Grisos, his monthly radio show on a local station, where he plays and discuss about ambient, techno and anything in between as well as making some interviews.

David has recorded the following mix with that feeling of knowing that something huge is about to change in his life, just like what happened at .apart in a way. Hence the name translated into Catalan :)

A magnificent true personal musical journey where he captures with great sense and extreme delicacy a long list of antonyms such as fear-hope, uncertainty-desire…

To sum up overall, David shares the following poem:

"... The rocks crash, the puddles splash, the mirrow ripples, the calmness returns, so are the turning points of life that disrupt our world to only steer us onto a path more right than the one before, let the wind blow as it may, for it's only wish is to whisk you away to a destination where your heart will find a true home, a place where the doubts and confusion have no life supply, for when the turn is complete, a soul once lost, will be found, only to realize it was all part of the journey, and around the corner there is so much more to see ...

This is an exclusive session of Ylia as part of Mostra Barcelona Festival (@mostrabcn) for HOC radio. 
"Like a Moebius work, this seemingly unconnected adventure is a brilliant laboratory of evidence. An asteroid of overlapping worlds, a space for abstract textures created by the eighth passenger, another space for earthly rhythms and songs of minimalist tribes. And so, constant superimpositions and overlaps of conceptual environments that, when you finish and look back, you will discover that there is no disconnection but rather the opposite."

Founder of Animah records (@animahrecords), Ylia (@ylia) is a musician, producer and Dj. She came of age DJing breakbeat raves in Andalucia while studying classical piano at the conservatory, and then moved to Barcelona to study modern composition and arrangements at Taller de Musics in Barcelona, becoming an intrinsic piece of the city musical ecosystem. She released her debut solo album 'Dulce Rendición' at Paralaxe Editions (@paralaxe-editions) while working on collaborative projects with Phran (@phran) as People You May Know (@peopleyoumayknowpumk); and with Darío del Moral under the name Bola del Desierto. She is also a member of experimental flamenco singer Niño de Elche's band, performing keyboards and electronics.

HOCast #101 x Mostra - Ylia

"Pure darkness, then a ray of light. The clock hand is heard in the background, a new life begins. A journey of intrigue, a roller coaster of emotions. Oscillating, heartfelt. The story begins, unfolds. It survives. It hides from predators. It is free. Every stage, every moment will be engraved inside the cave. Pure darkness, the hand of the clock is no longer heard. Teardrop. Ether. What a journey!"

 - Author's note:

For Postcard (FMOA Audio Postcards series)
by Kazuya Ishigami

release from: 
https://tbwb.bandcamp.com/album/for-postcard-fmoa-audio-postcards-series

The FMOA Audio Postcards series continues, with a new entry from one of my long-standing friends and collaborators. I have known Kazuya since my time in Osaka, which was essential to helping me understand the full possibilities of sound as a communicative medium. Though certainly no stranger to the region’s storied “noise” underground, Kazuya has waded into much broader and deeper waters - his growing body of work showcases a kind of Buddhist reverence for all sound phenomena as being mutually dependent, and as such we have results such as the great contribution for the postcard project.

In this compelling morphological study, sections of location recording, conversation and birdsong flow without resistance into dense clouds of computerized and electronic phenomena. While bearing some similarities to the “classics” of sonic flaneur-ism (see e.g. Luc Ferrari), this has a focused attitude unique to its creator’s experiences.

From his official bio:

“Kazuya Ishigami is a composer, sound designer, sound performer and sound engineer in the field of Electroacoustic/Acousmatic/Post-Acousmatic/Ambient/Noise, etc. He received his B.A. in Music Engineering from Osaka University of Arts and his M.A. in Urban Informatics from Osaka City University. He began playing with the tape recorder and making cut-up and collage works in early childhood.

From 1990 to 1994, he studied musique concrete and electronic music at Osaka University of Arts Music Department Music Engineering course. Since 1992 he has created under the name of DARUIN. He began using computers for composition and improvisation in 1994 with the programming language Max/MSP and others.

His pieces have been performed at DR (Deutschland Radio/Germany),WDR (Westdeutscher Rundfunk/Germany), CCMC (Japan), JSEM (Japan), FUTURA (France), MUSLAB (Mexico), SR (Radio Saarbruecken/Germany), HR (Hessischer Rundfunk/Germany), ISCM (Stuttgart/Germany), Spark (USA), NICOGRAPH (Japan), SILENCE (Italy), VII International FKL-Symposium (Italy), ICMC (2015_USA/TEXAS), Music From Japan 2020 (USA/NY) among others. He has an independent label, NEUS-318 and OMODARU, and has released more than 100 works.”

NOTE: the limited edition postcard is FREE with purchase of the digital album, with free shipping to anywhere in the globe.
