Alright, let's get back to what we're here for. Here's Deerhunter performing this song from their 2010 album Halcyon Digest on Conan.
Many bands that have multiple lead vocalists aren't too difficult for me to discern the differences - it didn't take me much time to understand Wolf Parade had two frontmen, or that Sonic Youth has two frontmen and a frontwoman. I didn't realize that Deerhunter had two, however, until I saw them open for Spoon at First Ave last year. Bradford Cox tends to get most or all of the attention paid to this band, but Lockett Pundt does sing on a few of their songs, including "Desire Lines".
And just because I want to, here's "Nothing Ever Happened" from back when there was a girl in the band.
