An eclectic mix of more than 200 headlining acts, ranging from indie-rock darlings The Flaming Lips to music legends like Peter Frampton and Bootsy Collins, will take the stage at this summer's Cisco Ottawa Bluesfest.

The 18th edition of Canada's biggest blues festival released its lineup Tuesday, spanning 13 days between July 5-17, with an off-day in the middle of the festival to allow fans, volunteers and staff to rest before the music kicks off again.

Among other acts confirmed so far were: Soundgarden, Huey Lewis & the News, Ben Harper, Steve Miller Band, The Black Keys, Death Cab for Cutie, Erykah Badu, Jennifer Hudson, The Roots and Girl Talk.

As far as Canadian content goes, fans will have their pick of seeing performances from: the Tragically Hip, Death From Above 1979, Bedouin Soundclash, Blue Rodeo, Billy Talent and Buck 65, also known as Richard Terfry, the host of CBC Radio 2's Radio 2 Drive show. More artists are still being confirmed.

The annual music festival site at LeBreton Flats Park, on the grounds of the Canadian War Museum, is expected to draw fans from around the world for what Billboard Magazine has ranked as one of the top 10 music festivals in North America.

Tickets go on sale to the general public at 10 a.m. on April 30.
