To label much of today's generic trance and nonsense dance-pop as techno is like calling the Corrs a rock'n'roll band just because they use guitars. There's a lot of misconceptions and prejudices still to clear up. But, in fact, what Wetmusik and their ilk do is seeped in purism. It's music gloriously free of compromise. There's no concession to the mainstream, which is what makes it so good.
Real techno is close to the original rebellion of rock'n'roll and punk rock.
And just because it's created digitally doesn't mean it can't be valid. Its producers still use human inspiration with musical ideas of composition and theory. The machines can't do it on their own. Just because the result is a track rather than song, with no traditional beginning, middle and end, doesn't mean it counts for less. Like a million drummers at once, basically.
