4Lyn was a rock band from Hamburg, Germany. 4Lyn began their career as Headtrip in 1995 as high schoolers. They recorded demos and played locally, and in 2000 a gig at the Ohrenschmaus Festival in Hamburg got them attention from label scouts. "4Lyn" is an acronym of sorts; 4 is the number of band members, and LYN stands for "Loud Young Nobodies". They released their debut self-titled record on Universal Records subsidiary Motor Music in 2001, and toured with Papa Roach, Thumb, Therapy?, Cosmotron, and Dredg.
