Frog Eyes performed with Destroyer in live shows and on Dan Bejar's album Notorious Lightning & Other Works. This collaboration led to the formation of Swan Lake, a "songwriter's project" with Dan Bejar of Destroyer/The New Pornographers and Spencer Krug of Sunset Rubdown/Wolf Parade.
From Wikipedia:Frog Eyes is an indie rock band from Victoria, British Columbia, Canada known for their highly idiosyncratic songs, which pit Carey Mercer's melodic falsetto whoops against an avalanche of guitar, keyboards, piano, and drums.
