In the non-traditional arena, many Welsh musicians have been present in popular rock and pop, either as individuals, (e.g. Tom Jones, Shirley Bassey, Dave Edmunds, Shakin' Stevens), individuals in groups (e.g. John Cale of The Velvet Underground, Green Gartside of Scritti Politti, Julian Cope of Teardrop Explodes and Andy Scott of Sweet, Roger Glover of Deep Purple and Rainbow), or as bands formed in Wales (e.g. Amen Corner, The Alarm, Man, Budgie, Badfinger, Tigertailz, Young Marble Giants), but not until the 1990s did Welsh bands begin to be seen as a particular grouping. Following on from an underground post-punk movement in the 1980s, led by bands like Datblygu and Fflaps, the 1990s saw a considerable flowering of Welsh rock groups (in both Welsh and English languages) such as Catatonia, Manic Street Preachers, Feeder, Stereophonics, Super Furry Animals, The Pooh Sticks, 60ft Dolls and Gorky's Zygotic Mynci.
