Event Horizon Records was a DIY label. It was owned by 'Modern Jazz' band Landscape, who after changing their musical style to something more dance-friendly went on to have a couple of Top 40 hits for RCA in 1981. The band issued a couple of EPs on their own label, 'U2xME1x2MUCH' (EVE-137; 1977) and 'Workers' Playtime' (EVE-139; 1978).  Those appear to have been the company's only releases.  Distribution was by Rough Trade and by Lightning. Landscape was an English band, best known for the 1981 hits "Einstein A Go-Go" and "Norman Bates." Formed in 1974, it toured constantly during the mid-to-late-1970s, playing rock, punk, and jazz venues and releasing two instrumental EPs on its own Event Horizon label. The group began experimenting with computer-programmed music and electronic drums in the late 1970s and early 1980s, making records in the emerging genre of synthpop. Landscape was composed of Richard James Burgess, Christopher Heaton, Andy Pask, Peter Thoms, and John Walters. Thanks to Robert Lyons For The Info.
