Rated this one before, but an excellent album with drummer Buddy Miles and bassist Billy Cox, that doesn't get enough credit sometimes, and is overshadowed by his earlier trio of masterpieces. This one delved more into heavy soul, blues, and proto-funk than psychedelia. "Machine Gun" is probably the best known track, but "Power Of Soul," " Who Knows" and "Them Changes," a solo hit later that year for drummer Buddy Miles, among others, are outstanding too.
