Portishead are releasing a single called 'Chase the Tear', with all earnings going towards Amnesty’s human rights work and all rights given to the organisation.

The five-minute track was previously only available as a download, but is set for a full international release on limited edition 12” vinyl on XL Recordings on 14 November. The vinyl comes backed with a new version of the song by Toronto band Doldrums ( www.endlessdoldrums.com ). The record will also come with a code to download the MP3 version.

The vinyl release will be available to buy online from Rough Trade and Piccadilly Records as well as the usual record stores and at Portishead live shows.

'Chase the Tear' was originally released in download-only form on 10 December 2009 (International Human Rights Day), with earnings to be donated indefinitely to Amnesty’s human rights work.When released in 2009 this had been the band's first release for years generating a great deal of profile for Amnesty International as fans all rushed to buy the track.

Andy Hackman, Head of Brand and Events at Amnesty International UK said:

“Portishead are undoubtedly one of the great bands of the last 20 years and we’re thrilled that they’re bringing out this modern classic on vinyl for Amnesty.

“We’re extremely lucky to have the support of some incredible artists in all fields, and Portishead’s involvement with Amnesty is definitely one we’re very proud of.

“Influential artists like Portishead are able to take the human rights message to new audiences and we hope that everyone who picks up a copy of this great song gets involved with our campaigning.”

'Chase the Tear’ is a reference to a paper tear-style “tear”, not a tear from an eye.
