AM radio was the soundtrack of the 1950s and 1960s, and before Wolfman Jack's broadcasts reached young listeners across the Mexican border, local rock 'n' roll and local radio DJs shaped a shared musical world. In Modesto, rock 'n' roll was on the air by 1953, and as teenagers cruised 10th Street, 1360 KFIV played the songs of the day, with dedications from Dwight Case at Burge's filling nights with doo-wop, rockabilly, and rock 'n' roll. George Lucas immersed himself in that music, buying favorite 45 records at Harley's records on J Street and at the store called Records at 14th and I, where listening booths let groups of kids hear new hits before buying them. Those records became the genesis of the American Graffiti soundtrack, which drew from the emerging rock 'n' roll of the late 1950s and early 1960s and featured artists from Buddy Holly, Chuck Berry, Fats Domino, The Big Bopper, and the Beach Boys to one-hit groups such as the Monotones, the Tempos, and Buster Brown, mixed with Wolfman Jack talk-overs. The soundtrack was certified Triple Platinum, reached number 10 on the Billboard chart, sold millions of records, and helped spark a new wave of 1950s and 1960s nostalgia that led to Happy Days and influenced Laverne and Shirley. Modesto also produced important local performers, including Kent Whitt and the Downbeats, the first Modesto-area rock 'n' roll band, and Roddy Jackson of the Merced Blue Notes, the first recorded rock 'n' roller from the area, whose 1958 song I Got My Sights on Someone New received national airplay.
