I can recommend the latest album, released Nov. 2004, from Italian group CONTRAPPUNTO PROJECT: "Elegie d'Inverno". I'm enjoying it very much: a very relaxing, somewhat minimal, soundscape.

If you like jazz, classical and Italian symphonic Progressive Rock then you may find this instrumental album very interesting. But be warned, it's on the very fringe of Progressive Rock. Here's the write-up from the record company (Mellow Records):

Elegie d'inverno is the Contrappunto project's third work in 5 years. This new album is very different from the others, you can't find typical progressive rock elements or vocals as on Subsidea and Lilith. Here you can listen to complicate instrumental textures mainly between acoustic instruments that remind XXth century contemporary music like Stravinskij, Gershwin and Piazzolla. Mixed with these instruments you can also listen to modern keyboards and sampled sounds....This mixing gives an idea of a very innovative and "progressive" sound!!
