Bassist Robin Sylvester was forced to sit out RatDog’s shows in Jamaica earlier this year due to an undisclosed illness. Lately, Sylvester has felt strong enough to play some gigs with Zero and this past Saturday the bassist joined RatDog guitarist Mark Karan during his performance. The show took place at Corte Madera, CA’s Book Passage and celebrated Deborah Grabien’s new book London Calling. Drummer Billy Lee Lewis also performed with the RatDog duo. Karan’s next show will take place at Phoenix, AZ’s The Compound Grill on October 15 as part of Brewtopia 2010.
