The Last Days by Scott Westerfeld

Strange things are happening: old friends disappearing, angels (or devils) clambering on the fire escapes of New York City. But for Pearl, Moz, and Zahler, all that matters is the band. As the city reels under a mysterious epidemic, the three combine their talents with a vampire lead singer and a drummer whose fractured mind can glimpse the coming darkness. Will their music stave off the end? Or summon it? Set against the gritty apocalypse that began in Peeps, The Last Days is about five teenagers who find themselves creating the soundtrack for the end of the world.

This was the only book by Scott Westerfeld that I wasn't crazy about. It was a companion novel to Peeps. (my review here.) To me, The Last Days was really hard to get through. And I didn't really like the constant changing of perspectives. I think they helped a bit, but Im just not a big fan of it.
I have read many wonderful books by Scott Westerfeld, and I wish I liked this one more.
