Influential indie-rock group Grandaddy have announced a 20th anniversary salute to their breakthrough third LP, 2003’s Sumday. “After many years of hammering away at writing and recording as Grandaddy, Sumday seems to be the center of it and where it all peaked. To the journalists we were, ‘On the verge of greatness, underrated, overlooked, unsung.’ It was a tumultuous and exciting time for us for sure. Also very exhausting,” Jason Lytle said. Grandaddy formed in 1992 and have released five official LPs, most recently 2017’s Last Place. Grandaddy members include Jason Lytle, Aaron Burtch, Jim Fairchild, Tim Dryden, and the late Kevin Garcia, who passed away in 2017.
