On July 26, Agua Dulce will take the stage with salsa, merengue and Latin funk. On Aug. 2, the U.S. Navy Big Band will perform. Rockola, a ’60s and ’70s band, will follow on Aug. 9. Thunder Road, a tribute to Bruce Springsteen, finishes the show on Aug. 16. PB Concerts on the Green is funded through $30,000 in grants from County Supervisor Pam Slater-Price. The Pacific Beach Town Council and Pacific Beach Community Foundation applied for the grants and organized the concert series.
