It appears all but one of them might still be laughed at. Only one has gone on to be any sort of prominence in the music world.
The bass player Didy Mackel has been in Iron Angel since 2015 and they've released some really cool thrash/speed
They had an album either last year or the year before but they are probably one of those bands that fits under the heading of "they were better in the 80's"
Yeah and in Germany there was a shit load of thrash bands that didn't even make it out of the area because of the bigger bands getting all the limelight.
Not sure if that takes balls of steel or brains of mush, possibly both.
