Drum instructional DVD featuring drum performances by Terry Bozzio, famous for his work with Frank Zappa. Originally a video tape from 1988, this is the DVD version reissued in 2006. It's rare, as it's not widely available. I purchased this used a few years ago with a disc condition of B (with scratches and stains). As shown in the product images, there are noticeable scratches and stains in various places on the disc surface. I've watched it about twice, and there were no playback issues such as skipping or glitches. Only those who are okay with it playing without problems, please purchase. Please refrain from purchasing if you are particular about the disc's condition. Drummer Drum Instruction Rock Metal
