Oakland abstract hip-hop crew Anticon's secret weapon is the Chicago-born producer Jel, a master of the SP1200 sampler and widely regarded as a wizard of hip-hop production. The follow up to 2002's Mush release Greenball is Greenball II: Proud Parent of a US Marine, a self-released limited edition CD. Raw instrumental beats fresh out of the SP are layered with strange Marine Corps training dialogue. The outcome is like a homemade sonic collage, messy and unorganized, but also touching and brilliant at times. Included is Jel's sublime remix of DJ Krush's "Zen Approach," a treat for Jel fans and anyone interested in the future of instrumental hip-hop.
