On March 25, 1991, Spitz released their eponymous debut album. Its closing track "Hibari no Kokoro", remake version of the title track for their independent EP, was issued as a single on the same day. In the following month, the album cut "Ninoude no Sekai" got heavy airplay on radio stations in Osaka. Except for a number of shows　in small venues, they mainly concentrated on studio work for the rest of that year. Their second LP "Namae o Tsuketeyaru" came out just 9 months later from its predecessor, followed by their first concert tour started from February 1992.
