Wow, I wasn't aware that TesseracT had been around that long (2003). Good to know. We're they rocking the style from the very beginning? I say so because while Periphery are not as old, Bulb really influenced people as "Bulb" through his soundclick account (via forums like sevenstring.org and the Meshuggah forums) well before there was a Periphery. Either way, it's kinda interesting how the internet has allow a style/scene to evolve outside of regional confines. This is just they way of the world now. Sevens appeared on on 'Covenant' actually, and I'm pretty sure Crowbar predated any of this so far as "baritone" low tunings go in metal.
