Justin Bieber guitarist Dan Kanter will join Bob Weir at TRI Studios on Wednesday, August 28 for a special appearance. Kanter will also be sitting down with Weir and Steve Parish to chat and take questions from fans. Those that would like to submit questions can do so via Twitter or Instagram video by using the hashtag #DanGetsWeird. The show will begin at 7:30pm PT, though it will not be livestreamed. A later air date will be announced in the future.

Kanter, who has been touring as Justin Bieber’s guitarist for many years, is a longtime Phish and Grateful Dead fan. Last month, he joined Mike Gordon and Jon Fishman for an improvised set at Chicago’s Second City Theater following Phish’s rained out show at the First Merit Bank Pavilion. Kanter, who we interviewed last year, has also teased Phish while playing with Justin Bieber on SNL, as well as at countless Bieber shows over the years.
