The first actual bands to play Gothenburg styled stuff were Dark Tranquillity and Eucharist which both made their first demos in 1989. I think Dark Tranquillity was called Septic Boiler back then...
cool.. someone should make a thread asking how dark tranquillity feels to have been there when it started and now there are hundreds of bands influenced by them.
yeah for some reason I remember seeing the cover of the demo it was like a big white cover with "In Flames Demo 93' " If my memory is starting to serve me..........
