I haven't heard much recently, but I really like Selenography by Rachel's, which is a neo-classical indie rock collective that operates somewhat as a small chamber orchestra with viola, cello, piano and horns often mixed with drums/percussion, guitar and electric bass. Very nice album from 1999 on Quarterstick Records. It's a little more accessible than the two previous ones I have, Music For Egon Schiele and The Sea and The Bells, which are both more structured and orchestral in nature. The Sea and The Bells is excellent though and very recommended. I have both on vinyl and the sound is very good. I think Selenography is mostly recorded live with all the musicians present together in the same room and the CD has a nice sound.
Roger Eno's classical work is really nice too. Check out his The Flatlands album from 1998. It might be described as 18 chamber orchestra vignettes, somewhat experimental and ambient sounding, but relying on the sound of acoustic instruments for the ambience instead of the synthesized soundscapes his more famous brother often uses. The individual "songs" each have their own dynamics and flow but the overall sound is what I like most, almost like a series of sketches to tell a story.
