André, here's my short guide:
Kotonski:
Etiuda na jedno uderzenie w talerz (
Study for one cymbal-strike - the title is derived from the fact that the
entire material in this is piece is a recording of
one single strike of the cymbals) is obligatory as the first Polish electronic piece.
Tierra caliente - IMO, Kotonski's best electronic piece. Though you should bear in mind that he's generally one of the top Polish experts in the genre (author of a textbook on the subject), so his pieces are always at least good.
Penderecki:
Psalmus - a classic. Like it or not, it's in the canon.
Andrzej Dobrowolski: Penderecki wasn't the only Polish avant-garde composer, and if you ask me - he certainly wasn't the best of the lot. Dobrowolski was. Every single piece of his is worth a listen, they are all brilliant and, IMO, much better thought out than any piece Penderecki ever wrote.
Beautiful music - and it's not often you can say that of avantgarde pieces!
Schaeffer - safe to skip, IMO.
Wiszniewski - even safer.
Tomasz Sikorski:
obligatory! You've got to hear it.
Eugeniusz Rudnik: another expert in the genre. His stuff is even better than Kotonski's. Perhaps the
best Polish electronic composer. You may give Ptacy i ludzie a pass - the piece relies heavily on spoken word (in Polish).
Mazurek: these are
very short pieces, so why not try?
Knittel: I'm not very fond of him in general but
Robak zdobywca is a very interesting sort of electronic tone poem - so if you'd like to give him a try, that would be my piece of choice.
There's also a piece by François-Bernard Mâche (
Nuit Blanche) - obviously, he's not Polish.
The site is not exactly dedicated to Polish electronic music - it's dedicated to the Polish Radio Experimental Studio. This piece was created there.
