"Rare are the musicians who can even play Zappa's music, let alone make it live and breathe. So Thank the Lord for the GrandMothers of Invention."..."With very different Zappa eras represented, the GrandMothers have a wide palette of material to choose from."..."They served up vintage psychedelia - rock songs with surreal lyrics, jazz-like harmonies and melodic complexity, with flashes of wacky satire."..."Amazing virtuoso musicians, fun and funny."

The GrandMothers were formed in August of 2002, when four legendary former members of Frank Zappa's “The Mothers of Invention”, Napoleon Murphy Brock, Roy Estrada, Bunk Gardner, and Don Preston were invited to perform the music of Frank Zappa in Leipzig, Germany. It would be the first time that these esteemed “Mothers of Invention” alumni would be getting together to rehearse and perform classic Frank Zappa material.

Finally, on March 27th 2003, after 6 months of intensive rehearsals, The GrandMothers of Invention took the stage to a standing room only audience in Leipzig, Germany. This event was recorded, filmed, and released by Warner Classics in Europe, and has been broadcast and re-broadcast repeatedly on European television. Due to the overwhelming demand since then, they have performed more than 140 concert events across America, Canada and Europe, including performances in: Austria, Belgium, Bosnia, Croatia, Czech Republic, Denmark, England, France, Germany, Holland, Hungary, Italy, Norway, Switzerland and Wales. Each performance providing indisputable proof that "THEY CAN (AND DO) STILL DO THAT ON STAGE!"

The list of dates at clubs, concert halls and festivals is long, and includes headlining the Frankfurt Jazz Festival, the Zappanalle Festival, the Vancouver Folk Fest, performing classic Frank Zappa material with the Bergen Filharmonik Orkester in Bergen Norway, performing the orchestral music of Frank Zappa under the baton of Kristan Jarvi, the Ottawa Blues Fest, the Winnipeg Folk Fest, the Sarajevo Jazz Festival, the Winnipeg Jazz Festival, the Vancouver Jazz Festival, the Syracuse Jazz Festival and performing classic Frank Zappa material with string orchestra (the Trondheim Soloists) at the Trondheim Jazz Festival in Norway.
