The musical style of British Invasion artists, such as the Beatles, had been influenced by earlier US rock 'n' roll, a genre which had lost some popularity and appeal by the time of the Invasion. However, a subsequent handful of white British performers, particularly the Rolling Stones and the Animals, would appeal to a more 'outsider' demographic, essentially reviving and popularizing, for young people at least, a musical genre rooted in the blues, rhythm, and black culture, which had been largely ignored or rejected when performed by black US artists in the 1950s. Such bands were sometimes perceived by American parents and elders as rebellious and unwholesome unlike parent-friendly pop groups, such as the Beatles. The Rolling Stones would become the biggest band other than the Beatles to come out of the British Invasion, topping the Hot 100 eight times. Sometimes, there would be a clash between the two styles of the British Invasion, the polished pop acts and the grittier blues-based acts due to the expectations set by the Beatles. Eric Burdon of the Animals said "They dressed us up in the most strange costumes. They were even gonna bring a choreographer to show us how to move on stage. I mean, it was ridiculous. It was something that was so far away from our nature and, um, yeah we were just pushed around and told, 'When you arrive in America, don't mention the war! You can't talk about the war.' We felt like we were being gagged."
