Carson Daly has been pretty hands-on when it comes to getting good, up-and-coming musical acts on his show. Last Call with Carson Daly is currently cycling through a series of reruns from the past year, but the ones that are re-aired offer a glimpse of 2009's highlights, those performers you should have checked out if you missed them. Tonight's episode features Swedish indie pop singer Lykke Li, who released her full-length debut in 2008 and reached No. 24 on Rolling Stone's list of the 100 Best Songs of 2008 with that album's single "I'm Good, I'm Gone." She performs the song along with "Little Bit" and sits down to have a chat with Daly on the Wednesday night show. I suggest you tune in. Wed., July 29, 1:30 a.m., NBC. — Leilani Polk
