According to Karl in a recent interview, they could follow up OWB immediately with a much more up-tempo techno release with the tracks they had lying on the shelves that didn't make the album. I'm guessing that includes Bamboo and possibly tracks like Always Loved a Film.
So yeah I'd definitely pay for that. No need to give everything away for free. While I'm not complaining (too much) about the ambient-ness of OWB it would be a shame if the beatless experimental stuff would be the only style left that actually get's released. (between all the riverrun releases, including the 2 soundtracks and OWB, there's only a handful of tracks you can actually dance to).
I don't know how much truth is in Karl's words though, since if they do have these kind of tracks, they sure haven't been playing any of them out live except for Bamboo, even though they've been playing loads of new Darren Price tunes.
