They actually had four albums.  Their first, 'Neptune', came out on Cobblestone, then 'In My Youth', 'Rebirth', and 'Motherland' followed on Muse after Cobblestone reverted to Muse.  I agree that 'Rebirth' is the pick, but all are good albums, and only 'In My Youth' saw CD issue.  These albums would have made a nice Mosaic Select back in the day.

Jazz Dispensary with another good pick.
