Fans of live bootlegs are well aware of the quality imbued within those pre-FM broadcast captures of the Ultrasonic Studios concert series for the influential Long Island rock station WLIR. And now, one of the hottest performances to emerge from those storied sessions in Hempstead, N.Y., is seeing a proper commercial release with this scorching two-disc set from the mighty Tower Of Power during their on-air appearance on May 14, 1974. In town to support their then-brand-new fourth LP Back To Oakland, this classic TOP lineup with the great Lenny Williams on lead vocals runs through their freshly streeted masterpiece with aplomb, digging into nearly half the record with fevered renditions of “Oakland Stroke,” “Squib Cakes,” “Time Will Tell” and “Man from the Past,” in addition to such choice back-catalog cuts as Bump City’s “You’re Still a Young Man,” “Soul Vaccination”—from their eponymous 1973 album—and a near 19-minute jam on “Knock Yourself Out” off their 1970 debut East Bay Grease. Hipper Than Hip is prime Tower at the peak of their powers.
