Helder Teixeira has spent years fine-tuning his music winning formula.

"I always had a non-dj approach of djing, in the sense that when playing i am not focussing on making the floor go crazy or focussing on the idea of always keeping the energy level up, up, up!
But i am very passionate about sharing with the crowd what i think are the dopest records of the moment or the dopest classics.

In that sense i’m not pretending to be “right” or “wrong” and i will not make 100% of everybody happy, but i feel that my duty is to inform people of what’s really hot, would it be timeless classics or brand new records.
I’m always trying to present to people a little bit of the history of “my” beloved House and Techno , as i tend to do so by playing very personal “classics” not the Hits from the past but very unique jams that in my mind represent the essence of what is magic in House and Techno."


Born in 1980, Helder Teixeira sparked interest in music early, starting his career in 1992. Began to be known as Dj Narcotic. His musical style was techno and played at private parties for friends.

In 1994 opted for Acid House, playing themes of Phuture, Fast Eddie, DJ Pierre, DJ Camacho and many others. After just over a year, gives himself completely, the whole slope House!

Varzim), "Botequim" (Braga), "House Kaffé" (Braga), "Astória" (Braga), "Barbieri" (Braga), "Amo-te Braga" (Braga), "Black Jack "(Vilamoura)," Romania III (Vilamoura) "," Estação da Luz "(Aveiro) and events such as: The Week In A Paradise Called Portugal - 1996, Enterro da Gata 1998 and Queima das Fitas 2000, Mit Penha and Twins Praia.

House music é um estilo musical surgido em Chicago, nos Estados Unidos, na primeira metade da década de 1980. Há muitos mitos sobre como ocorreu o nascimento da house music, mas de fato nenhum deles detém fontes e nem ao menos se sabe quais foram os produtores que trabalharam com maior afinco no desenvolvimento da cultura house music. Muitos dizem que a house music é uma vertente da disco music e da electropop dos anos 70, pois foram estilos de música quase que contemporâneos1 . Frankie Knuckles é aclamado por muitos como o "pai" da House Music , ele que é um dos pioneiros deste gênero juntamente com outros nomes como Tony Humphries3 . Atualmente existem muitas sub-vertentes do house, tais como: funky-house, tech-house, disco-house, progressive house, electro-house, acid house, soulful house, neo-jazz-house, entre outros.4

O elemento comum de quase toda a house music é uma batida 4/4 gerada numa bateria eletrônica, completada com uma sólida (muitas vezes também gerada eletronicamente) linha de baixo e, em muitos casos, acréscimos de "samplers", ou pequenas porções de voz ou de instrumentos de outras músicas. Representa, de certa forma, também uma evolução da disco music dos anos 70. A maioria dos projetos (desenvolvidos por DJs e produtores) e grupos de house music têm como origem a Itália, a Alemanha, a Bélgica, além dos Estados Unidos e Reino Unido.

Tech house is a subgenre of house music that mixes elements of techno with house music. The term tech house developed as a shorthand record store name for a category of electronic dance music that combined musical aspects of techno, such as "rugged basslines" and "steely beats," with the harmonies and grooves of progressive house.[1][2] The music originally had a clean and minimal production style that was associated with techno from Detroit and the UK.[2] In the mid to late 1990s a scene developed in England around club nights such as The Drop run by Mr.C & Plink Plonk, Heart & Soul, and Wiggle run by Terry Francis and Nathan Coles.[1] Other DJs and artists associated with the sound at that time included Charles Webster, Bushwacka!, Dave Angel, Herbert, Funk D'Void, Ian O'Brien, Derrick Carter, and Stacey Pullen.[1][2] By the late 90's London nightclub The End, owned by the former Shamen rapper Richard West (Mr C) and Layo Paskin, was considered the home of tech house in the UK

Deep house is known for complex melody, use of unrelated chromatic chords underlying most sequences, and a soul, ambient, or lounge vibe to the vocals (if any). It is a style of house music that blends elements of Chicago house, 80s soul, jazz-funk and Detroit techno. Deep house commonly appeared as a genre in the early 90s with more melodic sounds gathering influences from soul, jazz and African beats. In the early compositions (1988–89), influences of jazz music were most frequently brought out by using more complex chords than simple triads (7ths, 9ths, 13ths, suspensions, alterations) which are held for many bars and give compositions a slightly dissonant feel. The use of vocals became more common in deep house than in many other forms of house music. Sonic qualities include soulful vocals (if vocals are included), slow and concentrated dissonant melodies, and a smooth, stylish, and chic demeanor.
