On the walls: the art you need to see this week

A lot of the galleries are closed for summer, but that doesn’t mean you can’t still go out and get your art on.

This afternoon, street art aficionado Cam Novak leads a bike tour to some of the city’s best murals and wall pieces, the tour’s third installment thus far. Meet-up July 11 behind Foufounes (87 Ste-Catherine E.), 6-10 p.m., weather permitting, $10/PWYC

The ongoing series of extreme painting shows at several galleries around the city continues this week, with the vernissage for Stretch, featuring works by Paul Bourgault, Pierre-Yves Girard and Andy Curlowe. The artists, like others in this emergent genre, are concerned with an excess of movement, often depicted in complex layers of brash colour and a very physical painting style. July 11-28, Galerie d’Este (1329 Greene), vernissage Thursday, July 11, 5-8 p.m.

While mostly the Belgo is pretty quiet, there’s a vernissage this week for Rhythmes Circadiens, a fundraising group exhibition featuring 20 artists. Vernissage July 11, Circa (Belgo Building, 372 Ste-Catherine W., #444), 3-5:30 p.m.

Hot Sluts and Poutine have been on the walls at BBAM! gallery for the last month, and the pair of smut-centred artists close out the show with a finissage on Friday, July 12. 3255 St-Jacques, 6-10 p.m.

A little farther afield in Beaconsfield, there’s a large show and sale featuring Shona sculpture, with Zimbabwean artist Simon Chidharara carving live on-site, for a family-friendly art field trip. July 13-21, Beaconsfield Park (288 Beaconsfield), 10 a.m.-8 p.m. daily

Finally, for those who like to play with their art, the Montreal Museum of Fine Arts released a free app in support of the visiting exhibition by mind-boggling surrealist sculptural glass blower Dale Chihuly. Chihuly: Utterly Amazing lives up to the name, so if you haven’t checked it out yet, you should. The app lets you create Chihuly-like designs by blowing into your phone’s mic, then playing with the colour and shape before editing them into larger sculptures. Exhibit on through Oct. 8, MMFA (1380 Sherbrooke W.), $8.70-$17.50; app available only in the Apple Store, free ■
