So far, as many others have said, I've got Dan Le Sac on my must see list. As Gabe put it brilliantly: like Ali G but funnier [and musically talented]. I'm assuming he was referring to Ali G specifically, not Sasha Baron Cohen in general, 'cause I agree about Ali being the least funny of his characters.
Also, MGMT turns out to be pretty fucking good. I'm going to see them this Saturday somewhere in LA, forget where.
