Warthur
A live album capturing a Japanese date on the Power to Believe tour. It's a very modern King Crimson set, focused mostly on live material from The Power To Believe and The ConstruKction of Light - the oldest song here is One Time, from THRAK. Whilst the studio version of The ConstruKction of Light may be one of Crimson's weakest studio releases (though the recent ReconstruKction of Light do-over has been a major improvement), the songs here from it shine, having benefitted from being refined through live performance for years, and the setlist overall is about as good a live album from 2003 King Crimson as I'd expect.
Is it absolutely world-changing in the way Crimson's pre-1990s work was? No, but a band can only be expected to rewrite the rules of rock music so often in their lifetimes. If you thought The Power To Believe was a decent studio release, you'll probably find a lot to enjoy here.
