KiSS 92.5 WHAM BAM
Speaking of Blurred Lines, we imagine a radio-sponsored concert headlined by the sexy-pants R&B crooner Robin Thicke and the girly singer Avril Lavigne will feature complicated queues for pizza and refreshments at Molson Amphitheatre. Given that the former attracts panty-tossing women and the latter attracts lip-glossed teens, the juxtaposition is as bizarre as, oh, let's say, Mr. Thicke onstage this past week with a twerking 20 year old. Not to give Ms. Lavigne any ideas. Aug. 31, 5 p.m. $17 to $88.25. 909 Lake Shore Blvd. W., 1-855-985-5000 or ticketmaster.com.
We Can Be Heroes
The Second City comedy troupe tweaks its cast from production to production, but almost unfailingly brings the funny. The new revue is one of the company's most hilarious in some time, with winning sketches on a medieval executioner whose heads roll too much, a dolt of a medical patent whose head is where his prostate gland should be and a bullied child comforted by an elderly man who is generous with his wisdom but won't pay for her Girl Guide cookies. Through January, 2014, $24 to $29. Second City, 51 Mercer St., 416-343-0011 or secondcity.com.
Canadian International Airshow
How long has this aerial spectacle thrilled Torontonians? Well, back when it first began, the Great Waldo Pepper was just the Pretty Good Waldo Pepper, and the stealthy Nighthawk striker wasn't even a blip on anyone's radar yet. This year, the 64th-annual affair goes sky-high with vintage dog-fighting relics, synchronized Snowbirds, and a stunt-specializing guy whose "Dead Stick" nickname provides much more information than we need. Aug. 31 to Sept. 2, 1 to 4:30 p.m. $115 (VIP seating), Lake Shore Boulevard West (south of the CNE), 416-263-3650 or cias.org.
This show of contemporary cacophony traffics in traffic, specifically at the audacious corner at Yonge Street and Dundas Avenue. On Saturday, a marathon of new music includes percussive acts coming from all directions, with the TorQ Percussion Quartet just one of the noisemakers. On Sunday, things move to the Music Gallery, where the University of Toronto Saxophone Ensemble blows a collective valve on works by Steve Reich and others. Aug. 31, 2 to 10 p.m., free, Yonge-Dundas Square; Sept. 1, 8 p.m., $5 to $20, 197 John St., contactcontemporarymusic.ca.
Hot & Spicy Food Festival
That old Jerry Reed lyric, "when you're hot, you're hot, and when you're not, you're not," is honestly one of the most self-apparent (if not outright useless) axioms we've ever come across. Be that as it may, Harbourfront Centre on Labour Day weekend is absolutely warm enough, what with all sorts of trendy tips, tamale-level dishes and an iron chef competition where things tend to get, well, heated. Aug. 30 to Sept. 2. Free. 335 Queens Quay W., 416-973-4000 or harbourfrontcentre.com.
