It's no secret that the guys in Relient K have gotten more and more serious with their past 3 albums, moving past some of the more light-hearted/goofier songs that were on their first few albums, but their new EP K Is For Karaoke is a return to form of sorts. Covering an eclectic group of songs (ranging from Weezer to Justin Beiber to They Might Be Giants), Matt Thiessen and company deliver the most fun EP you'll hear all year. From the pop-punk reincarnation of Cyndi Lauper's hit "Girls Just Want To Have Fun" to Thiessen's catching Bieber Fever on "Baby", it's the perfect lightweight music to blast in your car this summer. And for those who are sick of rock bands covering pop songs (RK also covers Gnarls Barkley's massive hit, "Crazy"), the group throws in some great covers of Weezer's "Surf Wax America" and They Might Be Giants "Doctor Worm." Make this EP a priority on June 28th and get ready to include it in all of your summer party playlists.
