Liam Gallagher went on Twitter Sunday to trash Suede and Manic Street Preachers, who just announced a co-headlining UK tour. The Oasis frontman didn't hold back, continuing his decades-long tradition of publicly feuding with Britpop rivals. Gallagher's beef with these bands runs deep, rooted in the competitive egos and musical turf wars that defined the '90s British rock scene. His willingness to air grievances on social media keeps those old tensions alive, even as bands from that era reunite and tour. For Gallagher, the Britpop wars never really ended. They just moved to Twitter.
