Well pjw, you made me do it. I had to find a link to an Italian prog band that plays mostly music by Zappa. This Riccardo Fassi Tankio Band recording is their only one I have but I assume it is representative. As much as many other things posted here recently it belongs in a jazz discussion. I find it fun and enjoyable.
