In addition to ROT & BLAU
i would add GRUN & GELB,
as essential CON , ZUG a
picture disc of The Red Cassette ,
GOLD , the CON lp (originally Ballet
Statique) reissued on Captain Trip,
Electronegativity & Charred Machinery
on Art Gallery , out of print but
WELL worth tracking down ,
CONVICTION is a fairly recent
work and very cool !
