We all know Aerosmith's Steven Tyler is one cool dude, but he just got even better.
While in Moscow on a current tour with Aerosmith for Moscow's 868th birthday, Steven Tyler stopped on the street to sing with a performer. I don't know about you, but I'd be losing it if that happened to me! Steven Tyler is one of my favorites.
Tyler strolled up to the guy and sang "I Don't Wannna Miss a Thing." It's so impromptu that Tyler's even a little off since he's never performed with this guy before!
It's a musician's dream come true and I'm sure this guy is still freaking out.
Watch below and just enjoy the presence that is Steven Tyler. He's a rock god and one hell of a vocalist!
