Agreed, especially about "Electric Ladyland". Plus, of course, anything at all by Neu!, early Cluster, Harmonia or La Dusseldorf. To be honest, except for "Neuschnee" and "Super" themselves, listening whilst under the influence was the only time I ever really appreciated the second side of "Neu! 2".
Also, Spacemen 3's "Playing With Fire" is a killer.
