Answer
Depeche Mode was the band where Vince Clarke served as the primary songwriter prior to his involvement with Erasure. Clarke played a crucial role in shaping Depeche Mode's early sound, co-writing many of their iconic hits, including "Just Can't Get Enough" and "New Life." His contributions helped establish the band's distinctive synth-pop style before he left in 1981 to form Yazoo and later Erasure.
