Zappa's "Blessed Relief", "Twenty Small Cigars", "Grand Wazoo" and "Waka Jawaka", along with countless others, is some of the most wonderful music I've ever heard. I saw him in concert three times and was amazed that he encouraged people to vote and had a voting registration area set up as you arrived at the venue. His testimony in front of congress concerning censorship of music is noteworthy (John Denver was with him) and a testament to what kind of a man he was. His last work at the end of his life, "The Yellow Shark" is, IMO, a final tribute to his true genius. Those who might dismiss him for his sarcasm and sexual innuendo are missing the true measure of his musical prowess. I have to say that it was Frank Zappa's music that first led me to John Coltrane...and from there into the rich and limitless world of jazz and elsewhere.
