I continue to come across these two names through various compilations and virtual crate digging. If you trace the origins you'll find that they cross paths with the Echospace camp from their earliest days under that name.
Their sound varies but I'd sum it up as sonic manipulations of the analog kind. A brief bio can be found here. They are spread far and wide so it's tough to know where to start but the obsoletecomponents bandcamp page is probably the best place to start to dig in to their sound. Most of the releases are 'Name Your Price' so there is no reason not to venture in.
A representative compilation can be found below so take a listen and track down the releases from which these tracks came. You will not be disappointed.
