Rory Gallagher's zigzag guitar riffs injected his beloved blues with a hot-wire energy and intensity, as heard on Taste's pummelling "Sugar Mama." His album tracks and live cuts push that rhythmic base further into angular ‘70s hard rock, with the punchy "Crest of a Wave" and "Follow Me" creating a hard-driving launchpad for both his rapier-sharp solos and grizzled bark.
