who added distinctive "wet" reverb, rapid alternate picking, as well as Middle Eastern and Mexican influences, producing the regional hit "Let's Go Trippin'" in 1961 and launching the surf music craze. Like Dale and his Del-Tones, most early surf bands were formed in Southern California, including the Bel-Airs, The Challengers, and Eddie & the Showmen. The Chantays scored a top ten national hit with "Pipeline" in 1963 and probably the best known surf tune was 1963's "Wipe Out", by the Surfaris, which hit number 2 and number 10 on the Billboard charts in 1965. The growing popularity of the genre led groups from other areas to try their hand. These included The Astronauts, from Boulder, Colorado, The Trashmen, from Minneapolis, Minnesota, who had a number 4 hit with "Surfin Bird" in 1964 and The Rivieras from South Bend, Indiana, who reached number 5 in 1964 with "California Sun". The Atlantics, from Sydney, Australia, made a significant contribution to the genre, with their hit "Bombora" (1963). Surf music achieved its greatest commercial success as vocal music, particularly the work of the Beach Boys, formed in 1961 in Southern California. Their early albums included both instrumental surf rock (among them covers of music by Dick Dale) and vocal songs, drawing on rock and roll and doo wop and the close harmonies of vocal pop acts like the Four Freshmen. Their first chart hit, "Surfin'" in 1962 reached the Billboard top 100 and helped make the surf music craze a national phenomenon. From 1963 the group began to leave surfing behind as subject matter as Brian Wilson became their major composer and producer, moving on to the more general themes of male adolescence including cars and girl in songs like "Fun, Fun, Fun" (1964) and "California Girls" (1965). Other vocal surf acts followed, including one-hit wonders like Ronny & the Daytonas with "G. T. O." (1964) and Rip Chords with "Hey Little Cobra", which both reached the top ten, but the only other act to achieve sustained success with the formula were Jan & Dean, who had a number 1 hit with "Surf City" (co-written with Brian Wilson) in 1963. The surf music craze, and the careers of almost all surf acts, was effectively ended by the arrival of the British Invasion from 1964. Only the Beach Boys were able to sustain a creative career into the mid-1960s, producing a string of hit
