I'm speechless. I can't believe it took me 40 years to discover this album, especially after immersing myself in so much similar music from the same era. Oh well, better late than ever, right? To cut to the chase, this is just great music. Stellar tunes played by Buddy and his equally talented musical partners. Funky, soulful, rockin' ... it's all here, and it's all powerful. Great, timeless music. You need this one too!
