Komprex is a better speedcore producer, look at the discogs of frazzbass and you will see that most of his speedcore tracks are done with other producers.
Also frazzbass is at the moment really into radiumstyle frenchcore which is not my styl
Komprex - La Spezia's Underground Terrorism
Komprex - Butching The Buried Ones also very hot
very nice terror
Komprex & Frazzbass - Following Da Fashion
Komprex & Frazzbass - Cum With Your Pain
And Frazzbass? Yeah well his chill and the co-productions are quite often a big success. But on his own he doesn't reach the big crowd.
Altough he has a good talent in making terror not so boring as most producers do. (That's my opinion)
