Music and sculpture are rarely blended so beautifully, as with this boombox built into the body of a double bass by artist David Ellis. Incorporating a four-way stereo speaker system, two vaccum tube preamps, a Crown power amp, and a Behringer equalizer, it's clear that the man is serious about his sound too. While it doesn't appear to include a built in iPod dock, it does come with one of the Apple players to provide a music source.
Strictly limited to a run of only three systems, you had better hurry if you want one. At $15,000 however, the price is definitely more in line with the art world than your typical boombox.
