Disclaimer: The following is most likely uneducated bs from a GYBE newbie. Take it for what its worth
Shokan, do you mean tracks as in individual songs? Or do you want album recommendations?
Either way, here are some recommendations:
1)Turn the speakers up, and the lights down
2)Expect GYBE songs to build up to climax slowly
3)I reccommend you start with the Yanqi UXO album, and the first track, 09-15-00, which within 16 minutes will determine whether you love GYBE or hate it.
4)If you want a good example of "something REALLY nightmarish and powerful" listen to Rockets Fall on Rocket Falls.
Dead Flag Blues from F#A# is also an amazing song, but for someone like me, it would have been a bit too much of a contrast if I listened to F#A# before Yanqi UXO.
Here's the order that worked for me:
1)Yanqi UXO
2)Lift Your Skinny Fists Like Antennas To Heaven or Slow Riot For A New Zero Kanada
3)The one you didn't pick for 2)
4)F#A#
