I'm late to this thread, and I have nothing to add to the speculation about the "big American album" that Steven's currently working on, but I'd like to say that I'm just now listening to the Lefsetz podcast, and I'm enjoying it immensely. I already admired Steven Wilson, mostly based on being a fan of his surround mixes, but he really comes across in this podcast as a down to earth music fan, as much as an expert. He's also very generous here with his knowledge, explaining his process and approach, with background on the projects and personalities he's worked with, in a very forthright, entertaining way. If you haven't listened to this yet, by all means do. It's well worth the time (pushing two hours) for any surround fan.
