National Health D.s. Al Coda

D.S. Al Coda is the third album by the progressive rock and jazz fusion group National Health. It is a tribute to former member Alan Gowen, who died of leukaemia in May 1981, and consists solely of compositions written by him. Most of these had not been recorded in the studio before, although "TNTFX" and "Arriving Twice" both appeared earlier on albums by Gowen's other band Gilgamesh.

National Health were one of those rare English progressive bands whose classic mid-'70s output still sounds fresh today. Their sound prospered on imaginative linear musicality, often in a jazzy format that emphasized extended instrumental solos. Arising during a challenging time when progressive rock was being overtaken by a tidal wave of punk, National Health featured members of other Canterbury and post-Canterbury bands Hatfield and the North (a band considered a Canterbury supergroup in itself), Gilgamesh, and Henry Cow. After the release of 1977's debut album National Health and 1978's sophomore Of Queues and Cures, the group issued 1982's D.S. Al Coda – an homage to keyboardist Alan Gowen, who died of leukemia in May 1981 – and then fell silent as its members pursued other ventures.
