Nova Scotian music tends to be pigeon-holed as "traditional", "Celtic", "folky" and a number of other descriptors. I mean, when your big exports are the Barra MacNeil's, Rita MacNeil, The Rankins, Anne Murray and the like, it's a pretty accurate call. BUT! My whole life and certainly the last little while, I've been working on my music library. A big part of it has been adding more Canadian content and a big part of that has been adding Maritime/Nova Scotian content. And while it's not a complete picture of what the province offers, here's some non-traditional, non-Celtic, non-folky stuff for you.
-Ashley MacIsaac: modern traditional (it's a weird idea, but listen to Hi! How Are You Today? The guy took tradition, broke the rules and made it something new)
-Classified: rap, hip-hop
-Carmen Townsend: blues rock, hard rock, folk rock, Badass Woman I've had the pleasure to work alongside
-Plumtree/Absolutely Nothing/Bontempi/Overnight/SISTER/The Lord Almighty's: pop-rock, pop punk, indie rock
-Jale: indie rock, alternative rock, Woman Led
-The Stanfields: Celtic punk, hard rock, country punk, the coolest description of "The bastard child of AC/DC and Stan Rogers"
-The Tom Fun Orchestra: indie rock, alternative rock
-The Town Heroes: singer/songwriter, indie rock, a couple of Hicks from the other side of the Island that really rock
-The Trews/One I'd Trouser: hard rock. And yes, they left for Ontario, but they're still Nova Scotians
-Joel Plaskett/Joel Plaskett Emergency/Thrush Hermit/The Tim Robbins Experience/Nabisko Fonzy: singer/songwriter, indie rock, folk rock, garage rock
-Sarah McLachlan: singer/songwriter, alternative rock
-Sloan: alternative rock, indie rock
-Christine Campbell/Campbell & Johnston: blues rock, hard rock, singer/songwriter
-David Myles: R&B, jazz, "folk jazz". He's a MP for Nova Scotia, but don't let that damn the man.
-Electric Spoonful: hard rock, garage rock
-Weekend Dads: indie rock, alternative rock
-My world will collapse if I don't mention Stan Rogers: folk music, country, singer/songwriter
-Garnet Rogers: folk music, rock blend, singer/songwriter
-Gordie Sampson: alternative rock, singer/songwriter
-Holly Cole: jazz, she's got a love and respect for Tom Waits, if that'll sell it to a stranger. Check out "Temptation" which is an entire Tom Waits cover album.
-Matt Minglewood/Minglewood Band: blues rock
-Matt Mays/Matt Mays & El Torpedo: indie rock, garage rock, hard rock
-Jimmy Swift Band/P.F. Station: alternative rock
