it's just annoying when work in progress versions are better than the finished product, like ALAF (ok maybe it's
still not finished).
In any case, they've been playing "in progress" material in the live shows pretty much from the very beginning of uw anyway, not to mention that even finished tracks get changed and keep growing when played live. A lot of people probably prefer certain live versions of tracks over their original "finshed" studio versions. This is just a part of what uw do and what makes them great. It keeps things interesting for us fans and for themselves as well.
remember it's all about
process.
