Fairly well-known in their own country but severely underappreciated everywhere else, Poland’s Kobong was a highly original progressive metal/math metal band active in the mid 90’s.  Resembling Meshuggah both vocally and in their penchant for polyrhythmic mayhem, Kobong produced songs full of jazzy chords, thrashy technical riffing and spastic time-changes well before it became ‘trendy’ to do so.  Add in crazed, heavily-accented Polish vocals, and you get something that’s both heavy hitting and just plain fun to listen to.

Kobong disbanded after recording two albums, 1996’s "Kobong" and 1998’s "Chmury Nie Bylo."  After much searching, I’ve concluded that it’s basically impossible to purchase a copy of either album, at least in the U.S, so I don’t feel too bad posting download links.  These may or may not work:

Kobong - "Kobong"

Kobong - "Chmury Nie Bylo" Part 1

Kobong - "Chmury Nie Bylo" Part 2

The song ‘Przeciwko’ was apparently used in the Polish soundtrack for "Trainspotting."  Check out the video for ‘Przeciwko’ on YouTube.  Several members of Kobong have also formed a new band called Neuma, which plays a similar style of music.
