The band started playing regularly in 1968 after winning the Danish national championship in "beat music". Their championship title paved the way for the band's first two single recordings, "Eyes and Ears" and "I Can't Talk About It Now". Sven Fenger left the band in 1969, after which Gnags continued as a trio, playing Danish festivals and in Amsterdam. The band moved to
Aarhus in 1971 and joined a commune. There they recorded their first album,
Paa Vej, which was released in 1973. The band had financed the album out of their own pockets, and they sold the distribution rights to the record producer and musician Johnny Reimar. Struggling to find a record label, Gnags created Genlyd Records in 1974. Ivan Oehlenschaeg Sørensen joined the band in 1973 and Per Christian Frost in 1974. Gnags released their second album,
Del af en ring, in 1974. Gnags created Feedback Studios in 1975, from which most of their subsequent works have been recorded. In September 2013, Peter Nielsen began performing a solo performance show. == Music style ==
