This Heat’s eponymous debut album, also known by fans as the 'blue and yellow', is a masterpiece of experimentation.

This Heat's exploratory practice was based on extended collective improvisation that incorporated not just guitar and drums, but also viola, melodica, organ, household objects, and broken toys. They used tape machines to stretch the fabric of time and creative mic placement to warp space. They were fuelled not just by formal restlessness but also by rage at consumer society.

Although widely considered to be Post-Punk’s finest, This Heat had actually begun performing at the start of London’s punk era. They developed new strange and volatile strains of avant-garde music that time has proved to be hugely influential, a blueprint for much that would follow.

Featuring material recorded as early as their first public performance on 13th February 1976 and compositions that appear on the 1977 BBC Peel Sessions, their debut album was finally released in 1979.
