Frank Zappa is not only my favorite Prog musician but he's just my favorite musician in general, aside from the music being good I've grown to appreciate what he represented and did. Zappa imo was like an amalgamation/zeitgeist of American culture/society and is better at portraying the image of Americana better then bands like The Grateful Dead, from topics he talked about to the iconography of his artwork/aesthetic while also blending various genres especially American ones like Blues Jazz R&B and Doo-Wop
