I don't often cover the kind of thing they play on KROQ here in Los Angeles---my KROQ days were also my methamphetamine days and my high school days, and as such are far behind me and thankfully so---but That Noise was brought to my attention and their cover of Kings of Leon's Sex on Fire improves upon the somewhat clumsy original in a multitude of ways.
Mostly they do this by stripping a lot of the 'rock' out of the song and replacing it with a vibe I'd compare most closely to HEALTH's Die Slow and various other yesteryear Nine Inch Nails dance remixes, soaking the whole song in a pensive late night post-clubbing vibe. Unlike the original, That Noise's version actually seems deserving of the ridiculous title phrase: the song now oozes slow burning sex appeal.
I do think it's weird that newcomers That Noise are covering a Kings of Leon song that's barely a year old, but when it's done in such a way that it improves upon the original so thoroughly (and I say this as someone who has listened to the Kings of Leon original way more times than I'd like to admit) that I can't really complain. Besides, it wasn't that many years ago (well, like, forty, maybe) that immediately covering an artist's popular song in order to piggyback your way into the charts on it was a common occurrence. If it's working for That Noise, good for them, especially because this cover rocks.
