Mike Silver first started making music on his computer when he was 12, and for much of his life kept it fairly private. In 2008, he won a remix contest and slowly began to take his music public, culminating in a series of orignal albums and EPs (his latest, Exercises, was released on Tuesday). Under the name CFCF, he's built an impressive and wide-ranging body of production (he calls his genre "atmospheric electronic music with cinematic undertones"), but his music still retains a certain bedroom quality — an implied quiet, a sleepy intimacy, the close-quarters sensation of a private conversation.
