I've never followed their solo careers, although I love almost all of Don's stuff that I've heard. Must buy his albums at some point. I only have Glenn's albums, except the cover album. So I'm not waiting for solo albums from them.
But I felt really frustrated when Joe wasn't really playing on LROOE. The most spine-tingling guitar moment on the album came from him (the solo on the title track), and the most fun moment (LGTIT). But it wasn't enough.
