If you're in California at this time, I would personally go see Prince who is playing 21 nights the Los Angeles Forum. IMHO, the best guitarist and live performer in the world. Prince headlined Coachella two or three years ago IIRC.
Tickets are only $25 as he explained: "$25 is what we used to pay for concerts. Then somebody called TicketMaster came in. Now we're showing who the real ticket master is and putting the right price on it."
