A band like this doesn't just get content and play a song they same as the studio release every time, so it's great that this connection includes some live tracks, even if it's only a few. "Here 'Tis" benefits from the live energy, and "Smokestack Lightning" shows where the band can go outside of the constraints of a pop single. Where most of the tracks are two and a half minutes, this one goes close to six as they play with arrangements and solos.
Perhaps they were overshadowed by The Beatles and Stones, but songs like "Certain Girl", "Honey in Your Hips" and "I Aunt Got You" match up with what either was doing, at least in the early part of the sixties. To me, the best is "Heart Full of Soul", a blues-inspired tune that has a really intense tone. More traditional blues like "Train Kept A' Rollin'" and "new York City Blues" also benefit from their dense, electric-driven sound. "Shapes of Things" feels like a predecessor to the psychedelic movement that would come shortly after.
This was a band that was not afraid to experiment, and that lead to some great musical innovations. The band gets a bad rap as kind of a footnote from the British Invasion, but this set is a start on helping show how great they really were. They are Rock and Roll Hall of Famers, but they somehow still feel underappreciated. Take a listen to this set and hopefully you'll be able to appreciate them better. Look for their live albums, too.
