Ruben and The Jets is a band created by Frank Zappa, a renowned American musician, for his 1968 concept album "Cruising with Ruben & The Jets". Notably influenced by 1950s doo-wop and rock and roll, their music is replete with harmonious backing vocals, simplistic lyrics, and playful melodies, reflecting Zappa's fondness for the era's sound. Although a fictional group in its inception, Ruben and The Jets later materialized into an actual band, continuing to perform Zappa's compositions and contributing significantly to the nostalgic revival of doo-wop in popular music.
