On Saturday December 13, the Rex Foundation will celebrate its 25th Anniversary. The organization will host Sweet Music Everywhere, a concert that will take place at the Warfield Theater. Peter Rowan will perform in a number of settings, appearing in the Rowan Brothers, Crucial Reggae and the Peter Rowan Blue Grass Band. Other Confirmed artists include Panjea with Michael Kang, Jackie Greene, Ramblin Jack Elliott and the Brass Mafia. Additional guests are pledged for the show and given the size of the venue as well as the Rex Foundation’s origins as the Grateful Dead’s official charity, it is certainly not out of the realm of possibilty that some members of the group will appear as well.
