Wicked Lester was a rock band based in New York City. Two notable members were bassist Gene Klein and rhythm guitarist Stanley Eisen. Originally formed in 1970 as Rainbow, the band changed its name to Wicked Lester in 1971 to avoid confusion with another local band named "Rainbow". Although it secured a record deal with Epic Records and recorded an album, the deal fell through and the band fell apart during 1972. Klein and Eisen, feeling that the band's failure was a result of its lack of vision and direction, decided to found a new band from its remnants. They changed their names to the respective Gene Simmons and Paul Stanley, auditioned a new drummer and lead guitarist, and formed the band Kiss by the end of January 1973.
