Once again this summer, 2 of the rock's most beloved acts will share a bill, embarking on another amphitheater tour. Last year these bands shared the stage, often w/ collaborations between both bands, with guitar god's Warren Haynes and Derek Trucks joining Ratdog on a number of Dead tunes, and Bob Weir adding vocals to the Brothers set. I saw 2 of these shows last summer, and they were spectacular. In this day and age, you will be hard-pressed to hear 4 hours of music this enjoyable on a summer day. Don't miss Bob Weir Ratdog w/ The Allman Brothers Band, tours this good are few and far between.
