Bassist Reed Mathis will introduce Electric Beethoven on Jam Cruise 15 with help from Todd Stoops, Jay Lane, Cochrane McMillan and Clay Welch. For now, Mathis is unveiling a long list of collaborators and has revealed one more in Phish’s Page McConnell.

In a post on the band’s Facebook page, the teaser clip features a picture of McConnell with a caption, “In 1808, Beethoven predicted that Page side would be rage side.”

Past collaborators have included Andrew and Brad Barr, Stanton Moore, Mike Gordon, Joe Russo, former Pearl Jam drummer Matt Chamberlain and many more.
