Evan Bluetech，简称 Bluetech，是一个以创作电子音乐为主的音乐制作人，音乐风格以 Downtempo 与 Ambient music 音乐为主。但他的音乐风格也是多样化的，所以也会在他创作的作品中听到更多不同类型和风格的音乐。2003年，在 Truffle Records 推出了他的第一首单曲和第一张专辑《Prima Materia 第一物质》，从此，他一直很幸运，有机会连续推出更多的作品。2004年，在他朋友的帮助下，进入 Native State Records 唱片公司旗下，后面的专辑都是在这家公司发行的。
 
Evan Bartholomew, under the moniker Bluetech, produces his unique style of experimental noise from San Diego, CA. Classically trained on the piano for public performing, Bartholomew deviated from the traditional sounds and began to express the rhythms that sprouted from within him, and Bluetech was born. This resulted in his interpretation of nature's expression of being, a sound that is dronal ambient, downtempo, improvisational. He devoured the electronic potentials for musical expression and conveyed it in IDM, digidub, and psychedelic trance.
 
Bartholomew created and runs his own art collective in San Diego and does commercial sound design and production for both national and regional clients. He also writes and produces his own songs. &The Rubicon&, &Prayers For Rain&, and &Mezzamorphic& originally appeared on an EP released by Truffle Records, and brought the name Bluetech to a larger audience. In September 2003, these songs appeared on Bluetech's first album, Prima Materia, released by Waveform Records.
