Elvis Costello is back in Barcelona five years after his last visit. He's coming armed with his greatest hits, and taking a musical look back at his extensive career, along with his band The Imposters. One of the most influential writers of all time, Costello has recorded more than 30 albums and has worked with the likes of Paul McCartney, Tony Bennett, Brian Eno, Bill Frisell, Buch Bacharach and Rubén Blades, among so many others. He's joining in the Pedralbes Festival with a good dose of pop, rock, new wave, country and punk, playing every instrument he touches with precision, be it guitar, piano, bass, drums or harmonica. And wearing those glasses, of course.
