Bongo Fury, arguably, is among the more shape-shifting albums in the immense Frank Zappa catalog. With this special 50^th anniversary edition, it gets its day in the sun. Part live, part studio, part Captain Beefheart, part Mothers, all Zappa, the record has always been a bit of a multi-faceted amalgam more than a neatly cohesive piece. Yet, with this expanded box’s inclusion of two complete 1975 Austin, Texas shows that provided the initial source material, it offers a whole new context for its colorful collision.

The concept of Beefheart’s rolling-gravel vocal, eccentric lyrical approach, and jazzbo noire coupled with the rebuilt Mothers of the mid-1970s appeared tantalizing enough for Zappa to give it a tour’s worth of effort. That, and the fact that the motivating factors for the trek, in the first place, were certain impending contractual and financial concerns. This wasn’t necessarily an organically inspired collaboration at the time, despite Zappa’s longtime friendship with the Captain, and their notable previous work together, particularly on Zappa’s Hot Rats. Instead, it was more a creative solution to a problem.

Regardless of the origins, it’s a rather curious listen, at times magnificent. There is Beefheart’s pulsating and poetically greasy blues. There is the delightful musical dexterity of the Mothers, including the debut of drummer Terry Bozzio and the arresting slide guitar of Beefheart’s mate, Denny Walley; the latter providing, in his essay included in the extensive booklet, details of the events. And, of course, there is Frank Zappa—guitar wizard, demanding maestro, and charged host empathetic to his audience enduring the sweatshop temps inside the Armadillo World Headquarters; there’s even a mid-show bomb threat that forces an evacuation.

Zappa finds a way to pull it together into the proper album that was Bongo Fury, sounding renewed here in remastered form. Still, it’s the four discs compiling the two full shows at Armadillo that are the more compelling reasons for grabbing this set. Zappa concerts were always a spectacle in some form, but to balance a trio—Zappa/Beefheart/Mothers—in this Texas big top circus takes a mighty spectacular ringleader.
