On Sunday Dead & Company guitarist John Mayer shared an image that was designed like a Kanye West album cover yet featured the lyrics of “You Enjoy Myself” by Phish. The guitarist wrote that he would be attending Phish’s Halloween concert on Monday night followed by a Kanye show on Tuesday. Last night Mayer indeed hit up the Phish show, where he dressed as a unicorn and had what he calls his first experience on the rail.

While John Mayer did perform at the Jammys over a decade ago, it’s been in recent years where he both fully accepted the jam scene and the jam scene fully embraced him. Not only has he been impressing on stage with Dead & Company, but he seems to have a good feel for the community and is open to peak musical experiences such as watching Phish cover Ziggy Stardust and sitting-in with Joe Russo’s Almost Dead. From the looks of his Snapchat, Mayer had a fantastic time last night and even headed for the front row to have his experience watching the quartet from the rail. Watch Mayer’s good times at MGM Grand Garden Arena in Las Vegas via his Snapchat:

He’s also helping to spread word of a very important lesson: please shut up when the band is playing. Watch “Star Man” and “Moonage Daydream” from Phish’s Ziggy Stardust set and head here for more.
