Although many of the performances were geared towards younger audiences—Miley Cyrus, Taylor Swift, and the Jonas Brothers belted out their signature songs—last night the Recording Academy doled out five Grammy awards to the critically-acclaimed collaboration between one-time Led Zeppelin lead singer Robert Plant and bluegrass chanteuse Alison Krauss. The duo claimed Record and Album of the Year for Raising Sand. Rapper Lil Wayne claimed four trophies for Tha Carter III and had a memorable New Orleans-inspired performance. Coldplay took home a Song of the Year trophy and two others for “Viva la Vida,” while British soul songstress Adele was heralded as Best New Artist. The show was overstuffed with 22 musical performances from U2, Jennifer Hudson, Katy Perry, and a very pregnant M.I.A., whose due date was last night.
