Since I'm too inept to figure out how to embed videos, I'll just link two here:
National Treasure Number 1: Devin Townsend (Vancouver)
He first entered the spotlight as the singer on Steve Vai's album "Sex and Religion". What followed was a long and varied solo career, as well as the formation of the band "Strapping Young Lad"... pretty much the heaviest metal ever recorded. His solo career is a extremely musically diverse, ranging from brutally heavy metal, to angsty alternative, to completely chill ambient. His talents don't end at song writing. His mixing and producing prowess is legendary, both skills that he has honed by making extremely liberal use of multi-tracking. This song is from his newest album "Epicloud". It also showcases the vocal talents of Dutch singer Anneke van Giersbergen, ex-vocalist from "the Gathering".
National Treasure Number 2: Tegan and Sara (Calgary)
This duo probably needs less of an introduction here. Frankly, I don't know enough about them to write a big, flattering summary of their career. But, they've put out some truly excellent stuff over the last few years. This is their new single "Closer".
