Making, mixing, mashing and mutating music with the help of digital workstation software can be a painstaking process. Hours can be spent touching up a few seconds of audio until it’s just right, and much work can be put into perfecting layers of sound so subtle that only listeners with a $400 set of headphones are ever going to hear it. Mixing with a nice set of turntables transforms the process into more of a performance art. The basic technical elements are still there, but the task is done in the moment in front of an audience with a low tolerance for mangled beats.
