Bands have been reaching outside of their influence bag to find those not-so-normal cover songs for quite a while. In the 90's The Gourds covered Snoop's Gin & Juice, Alien Ant Farm went MJ on us with Smooth Criminal, and and Dynamite Hack paid tribute the original gangsta Eazy E with their mellow version of Boyz In The Hood.
Here's a semi-new batch of obscure covers - originals are not included this time since pop music is evil and contagious.
Deer Tick - Beautiful Girls (Sean Kingston)
i love that John noticed the Doo-Wop undertones in this song an expanded on them - even breaking into Stand By Me at the end.
The Kooks - All That She Wants (Ace of Base)
buy Radio 1 Established 1967 (2007)
A perfect fit for these guys.
Nickel Creek - Toxic (Britney Spears)
Simply amazing musicianship/showmanship.
Forgive the quality - it's a youtube rip. Check it out.
