I just discovered this Japanese space-rock outfit, Acid Mothers Temple and the Melting Paraiso U.F.O. (great name!) via their album "Crystal Rainbow Pyramid Under the Stars." Very Hawkwind-ish, with trippy electronics and blistering guitar solos. In a more ambient vein, AMT member Kawabata Makoto's "Hosanna Mantra" is a tribute of sorts to Popol Vuh's "Hosianna Mantra," wherein he weaves ambient guitar drones, looped sitars for an Ashra-like effect. These are both on the Important label, which releases a lot of experimental/noise projects.
