I only found out about this show today!  It looks like Hollerado is coming back to Guelph this week.  They were here back in October with The Arkells.  This time they're playing Van Goghs Ear on Wednesday with The Goodluck Assembly.
This show isn't even listed on hollerado.com (but it is listed on their MySpace site)
This will be their first of only three shows on Canadian soil between a South American tour and an upcoming Chinese tour!  They're dubbing this tour the Half World Tour.
I first heard of them after someone sent me a link to their video for Americanarama.  Hilarious!  Check it out.
