new age prog. stay away from anything they've done in the past decade, unless you prefer wimpy synth-driven emasculated art-rock.
the early stuff -- really, the first three records -- are pretty decent space-rock albums, floydian without the great songs. the guitarist also gets compared to robert fripp, but he's nowhere near as inventive.
some prog dorks love these guys, so if you're inclined to liking shit like marillion and '90s floyd, maybe you'll dig 'em.
