The band released their debut single "Finetime" in July 1995, which went straight in at No. 17. The follow-up single "Alright", a song originally written and performed a handful of times whilst still in The La's under the original title "Fly On" became the band's first Top 15 hit in the UK, peaking at No. 13 in the singles chart.  The band's debut album All Change, released October 1995 was produced by John Leckie who had previously worked with The Stone Roses and The Verve and had also previously worked with Power in The La's. The album shot to No. 7 in the UK charts, reaching double platinum and went on to become the fastest selling debut album in the history of the Polydor label, outselling the likes of The Jimi Hendrix Experience, The Who and The Jam. A further two singles were taken from the album in "Sandstorm" (#8) and "Walkaway" (#9), both top ten hits.  A stand-alone single was released in October 1996 titled "Flying", which reached No. 4 on the UK singles chart, giving the band their highest chart position in the UK yet.  With their second album Mother Nature Calls, released April 1997 the "rockier material was now sounding looser and cockier in a Stonesy or Faces-ish way and the moodier tracks awash with melancholic atmosphere". The band worked again with John Leckie. The album peaked at No. 3, reaching platinum and stayed in the Top 40 for over 6 months. The album spawned three top ten hits in "Free Me" (#7), "Guiding Star" (#9), "Live the Dream" (#7) and one top twenty hit with the 4th single from the album "I'm So Lonely" (#14), a ballad written during a period of bleak loneliness in a Japanese hotel room. Power revealed that the album title was supposed to be tongue in cheek, because Mother Nature is always calling because of man's mortality, but also because he was on the toilet at the time he came up with the name. Although The Daily Telegraph proclaimed "Employing the spiritual terms of Power's lyrics, Cast may be the perfect Taoist band. They don't seem to try. Cast just are.", the album received largely mixed reviews in the press, Power later blamed this on the fact that it was more of a slow burner than the more instant All Change and claimed that a number of critics later told him that repeated listens had changed their perceptions of the album.
