Having broken up the original Mothers a year prior, Zappa released two albums in 1970, Weasels Ripped My Flesh and Burnt Weeny Sandwich, both constructed from the group's vast well of outtakes. While Weasels is packed with live material, Burnt Weeny contains more studio work. It's also less manic and over the top. Featuring Ian Underwood's virtuoso piano work front and center, this is an album for those who really want to experience what The Mothers could achieve as a searing art-rock ensemble. In this regard, the nearly 19-minute "The Little House I Used To Live In" is not to be missed.
