13 is the sixth studio album by English alternative rock band Blur, released on 15 March 1999. Jettisoning the Britpop sound of Blur's early career, 13 explores experimental, psychedelic and electronic music.
Recording took place from June to October 1998 in London and Reykjavík. The album marks a departure of the band's longtime producer, Stephen Street, with his role being filled by William Orbit. Relationships between the band members were reported to be strained, with members frequently missing from the sessions. Lyrically, the album is significantly darker and more innovative than Blur's previous efforts, being heavily inspired by Damon Albarn's breakup with long-term girlfriend, Justine Frischmann, which followed an increasingly strained relationship.
13 was released on 15 March 1999 and entered the UK Albums Chart at number one, making it Blur's fourth consecutive studio album to reach the top spot. The album was later certified Platinum. The album produced three singles – "Tender", "Coffee & TV" and "No Distance Left to Run". 13 received a nomination for Best Album at the 2000 NME Awards. It was also nominated for the Mercury Prize.
