The trend that will return after this cultural fad of extreme electronic music (house,dubstep,...electronica) will be a sharp return to a very old acoustic tradition with soul (spiritual, not blues or country folk christian gospel), and will go further back than the guitar. The lyre and koto will come back into vogue. The Second Delphic Hymn To Apollo : Dated 138-128 BC. One of the earliest manuscripts of music that we can still play and we know who composed it. It's made up of 10 songs that flow together into one composition. What's cool to me is the Greek musical notation of the time. Their musical notes were like punctuations for letters, just like Hebrew cantation, not the musical scales we've learned in music class. I'm neither Greek nor Hebrew, so this is even cooler to me because I don't take the cultures for granted since I didn't grow up in them. The meter, tempo, and key are all very foreign. I love love love the first few minutes, and then it enters a rhythm that I do like, but you probably need to be of the culture of the time or listen to the music for a while to really appreciate all of it. ALSO: If anyone has the name of the bands that would go ahead of the Ottomans scaring the crap of their enemies playing music, please tell me. I think this type of military band starts with an M (mizer, mitre, something else?). I love the music, it's so powerful. Could you imagine opposing an army that is thundering with footsteps, AND playing beautiful, crashing, imperial music while they WALK TO KILL YOU AND DIE. All the while listening to cool tunes. If you see an army approaching you blasting music, you don't think you're fighting a sovereign, you're fighting a god. (Only example of this music I can even allude to is the "make way for Prince Ali" song in Alladin...sad).
