Previously On Lost are a Brooklyn-based band that watch each episode of the "Lost" TV series and quickly write a song about it, posting it online before the next week's episode. It's a great, very entertaining way to remind you of all the confusing stuff in the show's increasingly labyrinthine plot.
Musically it's quite diverse and theatrical, of definite interest to fans of, say, Sparks, or They Might Be Giants. Check out this girl-group/doo-wop pastiche:
Previously On Lost: Ballad of Sayid Jarrah
Their debut album, "The Tale of Season 4 and The Oceanic Six" is now available from their MySpace site. Yep, they start at season 4, so if you want to get hep to the first three seasons, you're on your own, sport.
