For some reason, Zac Brown Band has seemed to seep into the likes of rock music, be it teaming up with Chris Cornell or now joining forces for a jam with Aerosmith's own Steven Tyler.

Tyler joined the Zac Brown Band on stage at Fenway Park on Sunday night to perform two classics from the slew of Aerosmith hits.

Below are both videos of the performances, as Tyler ran through "Walk This Way" and "Sweet Emotion" with one of country music's biggest acts today.

Word also has it that the band even threw other covers into their set, including Zepplin's "Kashmir" and Temple of the Dog's "Hunger Strike".
