'Dragon's Pain Agency'[permanent dead link‍], a diary of events between the 10 June – 12 July written by the lead singer, was made available online from 16 July 2007 and includes information about recording developments, song titles, eating habits and progress through the computer game 'Black'.

The style was carried across to the official Sucioperro website, which was also designed by Chown, until the site was updated for the release of the band's third album, The Heart String & How To Pull It.

Although the official release date was 4 May, the album became available to purchase at gigs from 27 April to coincide with the start of a substantial UK tour.

A promotional copy of the album appeared on eBay on 13 April but was withdrawn by the seller later that day, apparently at the request of the record label.

A deluxe digital download, which contains extensive bonus material related to the Pain Agency era, was made available from the band's online shop in 2010.
