I first heard about Just Music thanks to Honeyroot, the short-lived but brilliant chillout spin-off from Heaven 17. Just Music turns out to have a small but impressive selection of ambient, leftfield, electronic, and off-beat artists to its name.
Apart from Honeyroot, their most famous acts include the now-legendary Jon Hopkins, Marconi Union, and Leo Abrahams. Hopkins, of course, has hit the higher reaches of the charts globally, although he seems to have also wandered onto bigger record labels in the process.
But small family record companies are really well worth celebrating. Just Music can be found here:
