Bee Gees' 1st is the third studio album by the Bee Gees, released 14 July 1967 in the United Kingdom, and 9 August 1967 in the United States. Despite the album's title, it was not their first full-length recording; the first was The Bee Gees Sing and Play 14 Barry Gibb Songs (1965). It was, however, their first album to be released 'internationally', as their first two LPs were only available in Australia and New Zealand. Bee Gees' 1st was the group's debut album for the UK Polydor label, and for the US Atco label. Bee Gees 1st was released on 14 July 1967 in the UK. On 9 August it entered the UK charts, on that same day, the album was released in the US, and it entered the US charts in 26 August. After its release, the band became more self-sufficient, producing and mixing many of their own releases.
Reflecting the group's early style, Bee Gees' 1st was a psychedelic pop album. The album cover was designed by Klaus Voormann who had previously done the cover for Revolver by the Beatles. Bee Gees 1st peaked at No. 7 on Billboard's Pop Albums chart and at No. 8 on the UK Albums Chart.
