Going to see this tonight, very excited. Sez Wikipedia:
Mantra is a composition by the German composer Karlheinz Stockhausen. It was composed in 1970 and premiered in autumn of the same year in Donaueschingen. The work is scored for two ring-modulated pianos; each player is also equipped with a chromatic set of crotales (antique cymbals) and a wood block, and one player is equipped with a short-wave radio producing morse code or a magnetic tape recording of morse code.

update: Whoa.
A composition by Iannis Xenakis, Pleaides was originally commissioned for Les Percussions de Strasbourg, to premiere at the Opera du Rhin in May 1979. A sextet for percussion, it is here performed by the Yale Percussion Group.
I’ve embedded the first video of seven above. Think how nice it would be to have a little avant-garde percussion concert right now at your desk! (Click the via link below to listen to the rest.)
