Sunday June 20 at 9PM sees two Montreal bands: Jane Vaine & Valleys stop in to Van Gogh's as part of Pop Montreal's POP OFF tour.  If I understand correctly, it's like Guelph's Hillside Festival taking a couple of Guelph bands and sending them out on tour prior to the festival promoting Hillside and Guelph.  I love the idea.
From a press release:
POP Montreal is proud to present POP OFF II, featuring two rising Montreal bands, Jane Vane and Valleys. The 15 date tour, which will kick off in Montreal June 11th, will include performances at renowned Canadian festivals NXNE, Works & Sled Island. Headlining the tour will be Valleys, recently signed to notable Montreal label Semprini Records (Call me Poupée, Pas Chic Chic). Their music can be described as intimate and enchanting experimental pop. They will be joined by fiery indie rocker, Jane Vain, who have been tearing down dance floors in Montreal for quite some time. Established in 2002, POP Montreal is a music festival and promotional company who has given several important platforms to emerging bands. Through the POP OFF tours, POP Montreal is now bringing the talent to cities across the country. This will be the second POP OFF tour of 2010.
