Original, and then-current, bassist Rob Wasserman died on June 29, 2016. On August 31st, 2016, Weir reunited Ratdog for a special tribute to Wasserman, at the Sweetwater Music Hall in Mill Valley, CA. Weir welcomed a number of guests to his show, including Steve Kimock, Mark Karan, Dave Ellis, Robin Sylvester, Jeff Chimenti and Jay Lane – all of whom were former and/or present members of RatDog. The band also welcomed Lukas Nelson and DJ Logic, who each sat in with the RatDog ensemble. The event marked the first time that guitarist Mark Karan and saxophonist Dave Ellis had played together in years. Both Karan and Ellis joined RatDog in the late '90s, with Ellis leaving in 1999 and Karan staying on until 2012.
