As a rule of thumb, before attempting to evaluate something, it's always a good idea to define that "something". Attempts to define art have been made for centuries. Some of these attempts are very serious and thorough, such as Leo Tolstoy's "What is Art?" essay, which was written in 1896--40 excerpts of its main points can be found here for your enjoyment (no, really, it's quite interesting). For this reason I'm declaring this article a deformity from the start--to avoid any disappointment from anyone stumbling upon it.
For many electronic musicians and sound designers a couple of synths, drum machines, and VST's along with a microphone and some creative sound sources are enough to keep busy. However, for many of us, there comes a time when the hiss of an old tape player and the crackle of an old record no longer satisfy the hipster in us desperately sniffing around for unorthodox sounds impossible to extract from prepackaged sample libraries or synths. This is when we fall victims to circuit-bending fever.
