This collection brilliantly commemorates the critically-acclaimed 2006 concerts which presented a collection of Zappa's rock-oriented compositions from the 1960s through the 1980s: this 2 DVD set is a tour de force of rock guitar virtuosity. Filmed in Portland and Seattle, this set is a guitarist's dream come true. Featuring Dweezil Zappa with Terry Bozzio and Steve Vai, a dash of Frank Zappa's social commentary and wit, this set is a document like no other available! Also featured are a mix of musicians who previously played with Frank Zappa including Mothers of Invention member Napoleon Murphy Brock. In addition, Zappa himself performs posthumously via synchronized A/V technology.
