The Ottawa Folk Festival will be celebrating their 20th anniversary this year and they’ve invited a collection of notable names to help them celebrate.

Lorde, The National, and Serena Ryder are just some of the acts revealed to be playing the 2014 edition of the five-day bash. The festival’s newly unveiled roster also includes acts like J. Cole, Neutral Milk Hotel, The Gaslight Anthem, Blue Rodeo, Foster the People, Joss Stone, Coeur de Pirate, The Wiggles and a whole trunkload more.

“I believe Ottawa music fans will be exceptionally pleased with what we’ve come up with this year,” noted festival programming director Mark Monahan. “It’s a fan-based lineup that reflects what fans are asking for. A lot of these acts are defining today’s music.”

The Ottawa Folk Festival is slated to take place from September 10-14 with early-bird tickets set to go on sale tomorrow.
