Britpop was a mid-1990s British-based music culture movement that emphasised Britishness. Musically, Britpop produced bright, catchy alternative rock, with significant influences from British guitar pop of the 1960s and 1970s. Britpop was considered a musical reaction to the darker lyrical themes and soundscapes of the American-led grunge music of the time, and Britain's own shoegaze music scene. The movement brought British alternative rock into the mainstream and formed the larger British popular cultural movement, Cool Britannia, which evoked the Swinging Sixties and the British guitar pop of that decade.
