The Astronauts were an American rock band, who had a minor hit in 1963 with "Baja" and remained successful for several years, especially in Japan. They have been described as being, "along with...(the) Trashmen, the premier landlocked Midwestern surf group of the '60s." For most of their career, the band members were Rich Fifield, Jon "Storm" Patterson, Bob Demmon, Dennis Lindsey, and Jim Gallagher.

Surf music is a genre of rock music associated with surf culture, particularly as found in Southern California. It was especially popular from 1958 to 1964 in two major forms. The first is instrumental surf, distinguished by reverb-heavy electric guitars played to evoke the sound of crashing waves, largely pioneered by Dick Dale and the Del-Tones. The second is vocal surf, which took elements of the original surf sound and added vocal harmonies, a movement led by the Beach Boys.
