Saturday Night Wrist boasts some of the Deftones' best out-and-out metal tunes to date; ''Rats!Rats!Rats!'' in particular is every bit as urgent and unsettling as its title implies. On the handful of tracks where the quintet indulges its experimental streak, however, the results are more mixed. Sparse electro-funk number ''Pink Cellphone'' is impressive and impressively rude but jammy instrumental ''u,u,d,d,l,r,l,r,a,b,selct, start'' sounds like people just noodling around while they wait for their singer to arrive.
