A mostly mid 1990's style of British music that began with Suede's release of "Suede". It was greatly influenced by late 80's Madchester and Post-Madchester bands such as The Stone Roses, The Happy Mondays, The Charlatans UK and others. They also have very heavy The Smiths influence, along with roots in 60's style British Rock, and British Traditional Rock. Also, the rock magazine NME used to love them. Some early 2000's bands are Britpop like, but aren't at the height of the movement.
Blur, Oasis, Pulp, Supergrass, Kasabian, Kaiser Chiefs, Manic Street Preachers, Mercury Rev, (the London) Suede. Look out--- That band is Britpop!
