I realize he has a built in fanbase and plenty of back material from TAI, but isn't touring off a four song EP slightly difficult?
I don't think it will be difficult because, like you said, he has a fan base and can also play older material. I also heard that he's going to play new stuff he hasn't released. Regardless, I've seen plenty of solo shows of lead singers, etc. who play before they've released an album or any material. Hell, Anthony Green was selling out solo shows before he even released Avalon. Bill has to get back in the scene at some point, why not start now. I'm going to at least two dates.
