Arroyo Seco Weekend debuted on Saturday, June 24, at Brookside by the Rose Bowl in Pasadena. An estimated 25,000 music fans were on hand Saturday to see performances by Tom Petty & The Heartbreakers, Alabama Shakes, Dawes, Live, Jeff Goldblum & The Mildred Snitzer Orchestra, The Meters, Charles Bradley & His Extraordinaires, Roy Ayers and others. Fans wore their very best festival attire to Arroyo Seco Weekend and we photographed some of the most wonderful-looking people who attended. All photos by Mathew Tucciarone Photography.
