Tim Minchin
I saw Tim Minchin last night, and he was great! He's a phenomenal musician and very funny, although his work is not for the easily offended (however it is a must see for skeptics!). His show only runs through this weekend and then he's back to Australia. Great YouTube video here. (And, by the way, his show met all four of my criteria for good sound, although of course I had a few suggestions :-) ).
(It's a busy week for shows--tonight I'm seeing my friend Katherine Fong's band, and then Thursday I'm off to the Loser's Lounge.)
