Stright from the FrankBlack.net forum (semi-official);
"Moreover, a few new songs have been creeping their way into the (solo Frank Black" nightly setlists, including one song that has been rumored to be a potential future Pixies track (or perhaps one on the upcoming Eric Drew Feldman produced FB album...), "(Do What You Want) Gyaneshwar." The setlists appear to be growing as the tour goes on, so who knows what FB + co. might play in your town?
As well, forum member Apesy alerted us to Frank Black's MOG page. And what is this? If you look in "My Digital Music Collection" under "Frank Black" you see a folder called "Demos for Pixies". Along with "Gyaneshwar", there's a song called "El Rey De Hawaii" and one called "Storm". It's clear these are tentative titles, but still very exciting. Plus, Frank Black has a MOG (aka a music 'blog'). How cool is that"?
