Well, it should be billed as the "Chicago Tentet + 1" correctly. Blame the organizer for that!
+1 is Bauer, the most recent addition to the band.
And yes, Zerang's drumming is very tuneful and musical! was rather unfair only singling out Nilssen-Love above, but he was so amazingly powerful! Bauer, too... he's a weirdo and probably the biggest fan of the other guys, too... but his playing was fine. In the Zurich concert though, Jeb Bishop was outstanding! They had a little 'bone trio once, with Holmlander on that weirdo thing - magic!
What struck me as most amazing is the degree of musicality you get to hear within all this messy, blaringly loud music - even when they are all on fire, and all playing simultaneously, you get all these little shifts, duos and trios within the whole group building... I bet it helps a lot that they play acoustically and are hence free to move around!
Was that the case at the concerts you guys saw, too? No mics except for the tuba, and a pair of amps for cello and bass - but besides that, just purely acoustic sounds?
