On SHOW YOUR BONES, the Yeah Yeah Yeahs show themselves maturing as songwriters and musicians. Much more musically focused, they seem to have more of a handle on the self-indulgent pretentiousness that tripped them up on Fever to Tell. Karen O is an incredibly uninhibited and expressive lead vocalist, and Nick Zinner shines on guitar. The rhythm section is strong and the songs are instrumentally much more interesting than this group's last time out. The lyrics, though, are obtuse and ridiculous, bordering on self-parody. "What, what did you do to your back/Kept soft thoughts cut lips carry pin back/ Junk jump off too much talk/Old hope breeds/Cold needs/Undress cold keys," yelps Karen on "Honey Bear."
