I kinda shy away from most modern Gibsons personally. I feel their quality has degraded over the past 15 or so years, though a classic style firebird will always have a place in my heart.
Sleep, Candlemass, Acid Bath, and Woods of Ypres's more doomy stuff are consistent favorites of mine. I would add The Melvins on here but they're kinda hard to lock on one definite area of music.
