RZA celebrated his 56th birthday by attending a Phish concert at Boulder’s Folsom Field. During the show, drummer Jon Fishman shouted out a birthday greeting to RZA, prompting Trey Anastasio to play a "Happy Birthday" riff on guitar and shout "Wu-Tang forever." RZA also hung out with Phish backstage and even got to play Anastasio's guitar. Phish's Instagram account shared photos of the encounter, quoting Wu-Tang Clan's "7th Chamber - Pt. II" in the caption. The birthday acknowledgments can be seen in an audience video starting around the 4:15 mark.
