Epic was a local metal band from Houston, TX, formed in 2003. In 2005 they recorded 5 demos, collectively called 'Out of the Darkness'.
They've gone through a bunch of line-up changes, with only one original member left, and have since released two official albums.
I was luckily able to get a hold of their recordings while they were still available, after hearing this song on the radio and being impressed back in '05.
Line-up:
Carlos Fernandez: lead vocals and guitar
Eric Smith: lead guitar
Hannah Pearson: bass
Matt Pearson: drums and vocals
