Sample-clearance payback is sweet, for listeners. Apparently DJ Olive used some music by a group called Sounds from the Ground on one of his tracks. They call him on it, and by way of apology he offered/agreed to remix one of their songs. “Speed Bump Dub” is a nearly six-minute excursion by Olive posted at his myspace.com webpage (myspace.com/theaudiojanitor). It plays with the standard symbols of sonic depths (cymbals at the high end, bass at the low, synths in between) but is entirely enjoyable, even if you don’t know the original (MP3).
