When they are not creating kickass posters, 2/3 of Malleus are in the group Ufomammut. They are on tour right now and before they hit the road for the European part of the tour Malleus created a poster for the Ecate tour. The poster is an edition of 151.
They will be in the US in May and June so check out the dates and go see them.
