From Shut Up ‘n Play Yer Guitar Some More (1981).
Frank Zappa (lead guitar), Warren Cuccurullo, Denny Walley and Ike Willis (rhythm guitars), Tommy Mars and Peter Wolf (keyboards), Arthur Barrow (bass), Ed Mann (percussion), Vinnie Colaiuta (drums). The meter is 5/4, or 10/4 depending on how you want to break it up. Vinne Colaiuta is said by some to be the most technically proficient drummer in the world.
This track is part of my most notable acquisition this vacation: the triple album Shut Up ‘n Play Yer Guitar. It was originally released as separate but concurrent albums: Shut Up ‘n Play Yer Guitar, Shut Up ‘n Play Yer Guitar Some More, and Return of the Son of Shut Up ‘n Play Yer Guitar. The basic idea is all Zappa guitar solos, all the time. It has some of his best ever assemblages of musicians. I’ve been grooving on this in a major way. Fantastic stuff for Zappa instrumental fans.
