Rhea--The True Color of Titan's Lakes. Deep space stuff a la Phobos,Tau Ceti, Oophoi, etc. Got this at Groove Unlimited website.
Nik Tyndall--Plejaden Suite, Trance Dance. A couple of his early albums around the time of his Hearts of Space release called Lagoon. Sort of melodic and new agey, but although still very nice atmospheric music. My only criticism of his music is it sounds like all digital synths with preset sounds.
Bernd Kistenmacher--Totally Versmold. This is basically live versions of his Thoughts album, which I didn't have so very worthwhile.
