Led Zeppelin is the debut album by English rock band Led Zeppelin. It was released on 12 January 1969 in the United States and on 31 March in the United Kingdom by Atlantic Records. The album was recorded in September and October 1968 at Olympic Studios in London, shortly after the band’s formation. It contains a mix of original material worked out in the first rehearsals, and remakes and rearrangements of contemporary blues and folk songs. Led Zeppelin showed the group’s fusion of blues and rock, and their take on the emerging hard rock sound was immediately commercially successful in both the UK and US, reaching the top 10 on album charts in both countries, as well as several others.
