Music Notes: Radiohead Plays Roseland, Arcade Fire Wins Polaris, $5 MP3 Albums

Radiohead video for "Lotus Flower" from their most recent album, "The King of Limbs."

Radiohead playing two shows at Roseland next week and Arcade Fire taking home the Polaris Prize headline this latest edition of Music Notes. Also in this edition: last call for Amazon.com's $5 MP3 album salefor September.  

* Radiohead is returning to New York for two shows at Roseland Ballroom on Sept. 28th and 29th. Roseland isn't exactly an intimate setting, but it's much smaller than the arenas the band is capable of selling out. There have been a couple of presales for the shows, but if you misssed out on those you can get Radiohead at Roseland tickets here at 10 a.m. on Monday, Sept. 26th.

All tickets are priced at $79.75 ($65 base price plus $14.75 in fees).

Note: an announcement on Radiohead's website says: "There is a 2 ticket limit per household. All tickets will be available for pick up at will call the evening of the event beginning at 6:30 PM and entry into the venue is required immediately upon receipt. No tickets shall be distributed prior to the event."

You can also get a shot at winning tickets to the concerts by contributing to L.A. radio station KCRW (a very worthy cause). Enter for a chance to win Radiohead at Roseland tickets here (enter by 3 p.m. Eastern time on Monday).

Also on the bill with Radiohead are Four Tet and rocketnumbernine.

* Arcade Fire took home the 2011 Polaris Music Prize for best Canadian album, which could be considered something of an upset since the award prides itself on going to the most deserving candidate based only on artistic merit, regardless of commercial success. (In the past more well-known acts have lost out to relatively obscure artists; last year's winner, the francophone group Karkwa, beat out albums by Broken Social Scene, Tegan and Sara, and The Sadies.)

Big congrats to Arcade Fire on taking home the Polaris (and the $30,000 prize).

* Amazon.com's $5 MP3 album salefor September is in its final week. If you're looking to expand your music collection on the cheap, you'll find albums there by artists including Mumford & Sons, The Decemberists, Feist, Fitz & the Tantrums, Regina Spektor, the Yeah Yeah Yeahs, Blind Pilot, Surfer Blood, Richard Buckner, and TV on the Radio.
