Queens of the Stone Age - for the opening 3 tracks on 'Songs for the deaf' alone is enough to make QOTSA a fave
Allman Brothers up to Eat a peach, Sisters & Brothers. Duane and Dicky Betts, The greatest of all guitar pairings
Molly Hatchett - Danny Joe Brown stuff, before they became AOR.'Flirting with disaster' toppermost boogie album ever.
ZZ Top - up to 'Eliminator'. Billy Gibbons is one seriously underrated guitar stylist
Lynyrd Skynyrd - 'Gimme back my bullets' was a bit weak but all the other albums of the Ronnie van Zant era were top notch.
Parliament & Funkadelic in the 70s. serious grooves, hot chops, off the wall lyrics and arrangements, top playing. The only downside - indirectly spawning the incredibly sh*te Chili Peppers.
Tower of Power, their funky Warner period up to '76. The best brass section ever bar none and one of the hottest rhythm sections in history
