Their songs are party starters, their rhymes are smarter, funnier and tighter than most and their contribution to the evolution of hip hop and rock music is immense.
There was a significant evolution in the career of the Beastie Boys, both in terms of their music and personality. The band's early misogynistic lyrics were hugely at odds with the socially conscious songs that came later. Likewise, their social and political activism belies the immature image the band had carved out in their early years.
But most importantly, much of their music is timeless. Their party anthems show a very healthy respect for great music of the past, while their style continually pushed the boundaries of modern hip hop, alternative and popular music.
