Last night String Cheese Incident’s summer tour with RatDog rolled into San Diego’s Viejas Casino. While the two bands flirted with collaboration over the weekend, it took until last night’s performance for the tour to truly hit its stride. After RatDog drummer Jay Lane joined SCI percussionists Michael Travis and Jason Hann during their drum jam, all of RatDog joined String Cheese Incident for its encore of ‘Goin’ Down the Road Feelin’ Bad.’ String Cheese Incident and RatDog will perform together tomarrow at Phoenix, AZ’s Dodge Theatre.
