Joni Mitchell’s 1971 classic Blue is a frosty collection of ten songs where the notoriously prickly Canadian alternated between reserved folk-rock (“Carey”) and mournful balladry (“California”). There was a point in high school when I declared it my all-time favorite album, and in a way it’s a very high school album. It’s all so quietly uncomfortable in its own skin, from the very first line (“I am on a lonely road and I am traveling, traveling, traveling, traveling.”) I can’t fathom what Mitchell would think about the latest project from Arc Iris. The Providence band have reinvented Blue, dramatically reinventing the album song by song. I’ve only seen some shoddily recorded clips online but it definitely sounds sonically inventive, full of drums and sampling and all kinds of other noises you don’t associate with 1971. The Matt Fraza Band opens.
