bassline driven house
A veteran of the SF underground, Kem started rocking underground parties in 1998 and maintained a busy schedule playing regularly at SF venues for many years. His sought-after and innovative style led to gigs in Japan, Australia, Canada, Mexico and cities across the U.S.

Today kem can be heard rocking dance floors at local favorite events such as FnF and Brass Tax (+Unison stream during the pandemic)

LeftCtrl —(also known as PolyGroovers, or DJ Zeel, real name: Konstantin Gredeskoul) started DJ-ing in the Bay Area in 1998, having been inspired and encouraged by @djethan Ethan Miller (FnF, BrassTax) among others. 

Konstantin produces downtempo music as PolyGroovers, (see https://soundcloud.com/polygroovers for more information).

Starting with the underground rave parties where he threw down Detroit Techno on vinyl, LeftCtrl played all over the Bay Area, with additional appearances in the UK, Spain, and Australia. 

He collaborated with @kem, Captain Tinrib, @henry-navarro and many more.

LeftCtrl's DJ sets feature a storyline, harmonic depth, and a smooth and deep, melodic, nearly always syncopated and groovy sound. Konstantin is an obsessively technical mixer, who admits to the most anal-retentive pitch-matching of the mixes, resulting in some of his entire sets played in the same key.

Since about. 2020, LeftCtrl refocused on the composition and production of tracks for the dance floor: house, progressive, and many genre bending tracks. Currently collecting sufficient portfolio for the upcoming releases in yet to be determined label.
