First things first: Tom Petty & the Heartbreakers will be playing the Hollywood Bowl on June 25 and Verizon Wireless Amphitheater on Aug. 22 with a little help from opening act Steve Winwood. Tickets to both shows go on sale Monday, and if you’re even a petite Petty fan, you should pick one up then.

Scratching a completely different itch among folks in a similar demographic, those time-signature abusing Canadians, Rush, also announced two shows: May 6 at the Nokia Theatre and May 11 at Verizon Wireless. Tickets go on sale Monday, but there’s no, umm, hurry to buy them.

In less geriatric news, the Bamboozle Left is coming to Verizon Wireless on April 5-6. You can pick up passes to see both shows (which include Paramore, Jimmy Eat World, Face to Face and the All-American Rejects the first day and My Chemical Romance, Anti-Flag, Chiodos and Armor for Sleep the second) here right now, or wait ’til Saturday to get one-day tickets.

If neither aging rockers nor cheesy emo bands are your thing, don’t fret. Other options await at Will Call. There are KCRW faves such as Ed Harcourt, March 10 at the Echoplex (tickets available now), and Kaki King, March 26 at the Roxy (tickets available Friday). There are hip-hop artists worth the drive to the Vault 350, including Pitbull and Baby Bash, April 3 (get tickets Saturday), and Del Tha Funkee Homosapien and Aceyalone, Feb. 20 (get tickets now).

But the winner? That has to be Harptallica, the all-harp tribute to Metallica, which plays the Malibu Inn on May 13 (tickets now). Why? With the possible exception of the Gregorian Masters of Chant, who play the El Rey on April 15 (tickets Saturday), there’s no one else quite like them.
