Sandy Bull's 1965 LP Inventions remains one of those legendary albums that almost no one has heard. Its impact, however, can be scene in the title of this new compilation spotlighting a great unsung hero of "psychedelic folk." "Blend," the 22-minute opus from 1963 that opens this disc, surely fits that designation, perfectly blending folk, jazz, and Indian influences into what Bull called "new guitar raga." An eclectic virtuoso who switched from acoustic guitar to banjo to Stratocaster to oud (mostly backed solely by jazz drummer/Ornette Coleman crony Billy Higgins), Bull was all over the musical map. Thus the beautiful, soothing bossa nova of "Manha de Carnival" gives way to German classical music, which is supplanted by a cover of Chuck Berry's "Memphis." The cream of Bull's first three albums can be found here. When those old records were in stores, it's a good bet Leo Kottke, Mark Knopfler, Richard Thompson, George Harrison, and Jerry Garcia were taking notes. --Bill Holdship
