For those who dig Roxy & Elsewhere-era Mothers, the second volume in the excellent You Can't Do That on Stage Anymore series is absolutely mandatory listening. As these archival recordings make clear, this particular line-up was in the zone all throughout 1974. Played in a scorching double-time, amazingly enough, the version of "Don't You Ever Wash That Thing?" found here is a frenzied behemoth hell-bent on obliterating skylines like Godzilla. In fact, most of the pieces that overlap with Roxy feel more amped up. Who knows, maybe Zappa really felt a need to blow away those wacky Finns.
