I'll begin with my favourite hardcore 6/8 song:
Thrice - Cold cash, colder hearts: thrice-cold cash and colder hearts (http://www.youtube.com/watch?v=8r4miMkVHDc#)
A huge power ballad:
Thursday - Autumn leaves revisited: Thursday - Autumn Leaves Revisited (http://www.youtube.com/watch?v=Qf4M1A68yGg#)
Classic, claustrophobic post hardcore (same artist as above) - At this velocity: Thursday - At This Velocity (http://www.youtube.com/watch?v=P3IagEQI75U#ws)
violent 6/8 at its best: glassJAw - Tip your bartender: Glassjaw - Tip Your Bartender (Video) (http://www.youtube.com/watch?v=sVEepmETMbs#)
The sad piece: The cure - Bare: The Cure - Bare (http://www.youtube.com/watch?v=JgJ_R959uec#)
Favourite deftones 6/8 song: Can't even breathe: Deftones - Can't Even Breathe (http://www.youtube.com/watch?v=u1WMpe05SaY#)
(by the way how can I do to post just the youtube link and if people wants to check it out the open it?)
uhm neither that glassjaw song nor the deftones one is in 6/8?
you mean a 6/8 beat right?
Yup, ternary tempos.
