Swan Lake is a Canadian indie supergroup^{[citation needed]} comprising Carey Mercer of Frog Eyes and Blackout Beach, Daniel Bejar of Destroyer, Hello, Blue Roses and The New Pornographers, and Spencer Krug of Wolf Parade, Sunset Rubdown and Frog Eyes. Originally playing under the moniker "Thunder Cloud", the group changed it to Swan Lake after discovering the previous name was already taken. The band released their debut album Beast Moans on November 21, 2006 through Jagjaguwar. The album was named by Mercer, after Krug described the sound as "a boar dying in a tar pit".
