Grand Wazoo
This 1972 album continues the mostly-instrumental, jazz-rock thread of Zappa's work, which began with HOT RATS and continued with WAKA/JAWAKA. It's a big-band setting this time, with lots of improvisation, with big brass, woodwind and percussion sections.  Sal Marquez, in particular, shines on trumpet.  Zappa-philes will also recognize names like Aynsley Dunbar, Don Preston and George Duke.The five lengthy tracks include the witty "Cletus Awreetus-Awrightus," the intricate title track, the rock-edged "For Calvin (And His Next Two Hitch-Hikers)," and the more lyrical "Blessed Relief." Packaging includes a Zappa narrative that gives these tracks their conceptual continuity. Zappa was temporarily giving his satirical side a breather (it would return in due time on OVER-NITE SENSATION) and making some of his more ambitious, if often overlooked, instrumental work.
