Austrian pop/rock duo Luttenberger*Klug consist of vocalist/guitarist Chrissi Klug and vocalist/keyboard player Michelle Luttenberger, who met at one of Klug's concerts and quickly developed a friendship. Teaming up as Luttenberger*Klug, the two girls recorded their debut single, "Super Sommer" (Super Summer), in 2005, and when they re-released it in 2006, it entered the Austrian and German charts. A follow-up single, "Vergiss Mich" (Forget Me), followed in fall 2006, entering the Austro Hit Top Ten at number one. Their pop/rock debut album, Mach Dich Bereit! (Get Ready!), was released in February 2007, reaching number five in the Austrian charts. The two girls and their band have played supporting gigs for fellow Austrian pop singer Christina Stürmer, the Sugababes, and teen rockers Tokio Hotel. ~ Christian Genzel
