There is a trend in what I might call the underground metal scene, or at least the underground extreme metal scene, with a lot of young bands making very technical metal. This is nothing view and it may have started with the Dillinger Escape Plan and there rise from underground heroes to forerunner of a new genre (this Math Metal, Mathcore thing). It is very interesting to see so much technicity coming from young musicians when ten years ago the nu metal scene took the technicity and agression out of a generation of listenners. And now, the next generation is enjoying a kind of music that is miles away from nu metal, with solos, overblown structure with multiple riffs and rythms and no trace at all of melody. I like some of these bands, Ion Dissonance, Psyopus or the End play a kind of metal that is very modern but can stilll stand on their own even if some of their influences are stil obvious (there is a riff from "the Running board", off the Dillinger Escape Plan's Calculating infinity, in a Psyopus song). Bands like Cynic or Atheist were there before all of this and paved the way for the music of these bands but there's no reason to slag these young bands for taking notes of what this bands have done for Metal and using them as influences. In fact, all this tech metal bands might be producing some kind of missing link between extreme metal and free jazz. After all, if there is one kind of music that is much more technical and with even more chaotic structures it is jazz related music (I don't want to say just "jazz" because there are so much sub genres within that term). Jazz musicians and Extreme Metal have already met and produced some very interesting childs (Naked City, Painkiller, both projects of free jazz saxophonist John Zorn) but there is room for even more experimentation. I hope that one day, all these very talented musicians will use more their talent at their full advantage and will throw away some of their Metal structures to spread their wings like Ephel Duath on their latest album (Pain necessary to know). Because when I listen to a band like Psyopus who features a very interesting guitar player with a kind of "unique" style of playing, I can hear his music becoming more and more complex. the Only problem ? Well, with so much experimentation, it will be more difficult to craft memorable songs and not just bursts of screaming with some over the top fret board actions.
