The first wave of acts for 2014 Ottawa Bluesfest has been released!

British rockers Procol Harum will perform with the NAC Orchestra on July 10 as part of the 20th anniversary edition of Ottawa Bluesfest at Lebreton Flats. It’s one of the more interesting shows included in this morning’s lineup announcement for the July 3 to 13 festival. Headliners include Lady Gaga, The Killers, Blake Shelton, Queens of the Stone Age, Jeff Tweedy, and Lady Antebellum.

Decades past are well-represented with appearances from 70s icons Foreigner and Journey, 80s hit makers Styx, Blondie, and The Violent Femmes, 90s throwbacks Third Eye Blind, Collective Soul, The Barenaked Ladies, and Moist, as well as contemporary indie acts such as Gogol Bordello, Young Rival, Jenny Lewis, Bonobo, St. Vincent, Royal Canoe and Andrew Bird. Hip-hop mainstays Cypress Hill will play the festival July 9 and Snoop Dogg (aka Snoop Lion) returns for a show on July 12.

You can review the lineup at ottawabluesfest.ca. The complete lineup will be posted on that site in April. Ottawa Bluesfest head Mark Monahan said another headliner is yet to be named, meaning Rumour-Fest can still continue for a few weeks. Some Ottawa Bluesfest enthusiasts were taking to Twitter with hopes that the yet-named headliner might be Beck. Headliners at this year’s Osheaga festival in Montreal include Jack White, Nick Cave & the Bad Seeds, and Lorde. Outkast and Arctic Monkeys are also on the festival circuit this summer.
