there are 2 bands that use the name Pills.

a) French dance experimentalists -- such as les Rhythmes Digitales, Air, Daft Punk, and Cassius -- have been sparking techno with their brash art-school ambience. Hailing from a tough Paris neighborhood, Pills joined their ranks. Pills released his debut album, Electrocaine, in 1999, and Musicsoldia was issued a year later. ~ Stacia Proefrock, All Music Guide

b) a San Francisco hardcore band featuring ex-members of Funeral Diner, Burial Year, Threatener, etc... they've released a 3 song demo "Not About God" in February 2011 which is available for free download @ http://www.pillsband.bandcamp.com
