Run DMC & Aerosmith - Walk This Way (1986)

The best musical duel of all time. Aerosmith vs Run DMC. Rock vs Rap. It was a tie, I guess. Everybody wins.
Still in the aftermath of Steven Tyler leaving the group after 20 years (maybe, or maybe it’s just rehab time. Poor Steven), I look back at this ‘rock marrying rap’ - often replicated, never quite recaptured - and I’m amazed at the pure energy and easiness of this song.
It was groundbreaking, and it’s easy to see why.
