Following the departure of Ryan Ross and Jon Walker for The Young Veins, Panic! At the Disco have acquired a new guitarist and bassist. The Cab’s Ian Crawford will join as the new guitarist, and the Brobecks’ Dallon Weekes has signed on as bassist. Spencer Smith told MTV that Crawford is the most talented guitarist he’s ever played with and that he and Brendon Urie are good friends with both Crawford and Weekes. Check out the new chemistry when  Panic! At the Disco visit the Comcast Center on August 6 with Blink-182, Fall Out Boy, and Chester French.
