I thought Matt sounded great at the Thekla - technically adept, and he served the songs very well. I've got the feeling that the band have put a lot of careful consideration into choosing a really good drummer.
It probably helps that he's into the music too, from what I hear (apparently he requested that the band close with Mean to Me, on Monday.)
I can't imagine that commitments with Beck will take priority over Crowded House. Beck is a big solo artist, but Matt is in a band now and a damn good one at that. All things being well, I think we'll see him for many years to come.
