Yes. Some people only know Frank because of daughter Moon's "Valley Girl" record in the 80's. But he could play guitar, produce, and compose like it's nobody's business.
Ike probably was his best singer (Flo and Eddie get honorable mention).
And for people who thought his lyrics were obscene, check out the almost-all-instrumental "Hot Rats".
It's nice that high school jazz bands are tackling "Peaches en Regalia".
To be honest, I'm not really a big fan of "Valley Girl," despite its success. I much prefer the stuff from the 1970s...speaking of which, I've just discovered the Flo and Eddie band that Zappa assembled. The "Just Another Band from LA" album is incredible. "Hot Rats" is great too...I especially love "Son of Mr. Green Genes" on side 1.
Apparently, Frank Zappa planned a reunion tour for the 25th anniversary of 200 Motels and he wanted to bring back Flo and Eddie, but sadly he passed away before it happened. Read in the link:

Can you imagine how epic that band would have been? Frank, Ike, George Duke, AND Flo and Eddie! I imagine that he probably would have had Chad Wackerman on drums, Arthur Barrow on bass, Ed Mann on percussion, Robert Martin on vocals/sax/keys, and the Fowler brothers (Bruce and Walt) on brass instruments. Maybe Napoleon Murphy Brock and/or Mike Keneally too? If that isn't an epic lineup, I don't know what is.
