The goal is simple: name three acts of this era you think are criminally underrated or unknown.
I'll start.
1.) Rory Gallagher: The fact that this man is not world renowned is beyond me. Highlights include "In Your Town", "What in the World", "I Could've Had Religion" and "Pistol Slapper Blues" from Live in Europe and "Walk on Hot Coals", "I Wonder Who" and "As the Crow Flies" from Irish Tour. "Garbage Man/Roberta" from BBC Sessions is also an incredible track.
2.) Peter Green: Before Fleetwood Mac was an AOR darling with songs like "Dreams" they were the most exhilarating, authentic Blues band to come out of the second wave of British blues. At the helm was likely the most gifted blues guitarist of his generation (all post war generations in fact): Peter Green. Highlights of the PG era, if you must pick a few, are all live tracks and contained on the Live at the Boston Tea Party and Shrine 69 albums. Notable ones are: "Jumping at Shadows", "Need Your Love So Bad", "Rollin Man", "If You Be My Baby" and, in the only performance of a blues song where an artist out-BB Kings the master himself, "Let Me Love You", where Green churns out the most tantalizing slow blues of the entire decade. These tracks are not to be missed. In fact, the entire Green era Fleetwood Mac catalog is essential listening.
3.) Cactus: This is the band that embodies the "Boogie" rock moniker of the early 70s better than anyone else. Jim McCarty is a freaking genius on the guitar and there is no one who represents the Motor City style of rock and roll better than him. The best recommendation I can muster is an out of print Rhino collection called Fully Unleashed: The Live Tracks, which contains some of the best hard/boogie rock of the entire 70s decade. Standouts are "Alaska", "Oleo", "Heebies Jeebie Medley" and "Bad Mother Boogie". Also their first two studio albums are phenomenal, with "Parchman Farm" from their eponymous debut and "Long Tall Sally" from One Way or Another as particular standouts.
Feel free to PM me for any of these tracks listed and I will do my best to hook you up.
