We don't even know how many times we've seen Modest Mouse over the decades. It's a lot well over two dozen times. But we are still looking forward to adding to that tally when this terrific alt-rock troupe returns for a co-headlining show with indie-pop stalwarts Flaming Lips at the Greek Theatre in Berkeley on Sept. 7. Dehd opens. Showtime is 6 p.m. and tickets start at $83, apeconcerts.com.
