You're probably here because you know her version of Hound Dog and want to know if there's anything else worth having by 'Big Mama' Thornton. Well you're in luck. If you like Hound Dog then this fine collection of rockin' Rhythm n Blues is going to be right up your street: 22 tracks and not a duffer on there. Obviously it all has a similar-ish sort of feel to it, and in the way of artists of the day, Hound Dog gets revisited at least in theme and attitude a few times here, but at least with enough variation not to get tiresome. Highlights for me include I Just Can't Help Myself, The Fish, Yes Baby (with Johnny Ace), Walking Blues (containing more than a hint of Otis Rush's My Love Will Never Die), and of course the aforementioned Hound Dog.
I can't say if this is the definitive collection of Big Mama's work as it's the only one I own. Probably there's more comprehensive ones available, but if you're looking for a single cd album at budget price I doubt you'll do much better. Go on, give it a try. What have you got to lose?
