in the 2005 vid the lead singer sounds like the one from Disturbed... but nothing else does (musically wise), they're usually heavier. So not exactly sure.
Listend to the K.L. one... no clue.
Heavy recomendations for lifting tunes:
Disturbed
Fear Factory
Mudvayne
Killswitch Engage
In Flames
Slipknot
Ebony Tears
Children of Bodom
