Poobah- U.S. Rock LP. U.S. Rock is the second release from the mighty Poobah (originally released in 1976). This album features ten tracks with Jim Gustafson, the Grand Poobah himself. This stellar LP delivers a resounding set of six string heroics that shows Jim sitting alongside the greats of the time, and shows why he is the Wizard of Heavy Psyche! 10 blistering tracks that are a mixture of early spine-rattling metal, groove-heavy boogie rock and healthy doses of fuzz splattered psych-rock. A total blowout of English-power-trio riffs brimming with thick layers of swirling lathered fuzz.
