Higher Learning which accompanies a hip-hop-generation-meets-white supremacists film is appropriately filled with clashing aesthetics, so that the juxtaposition of workaday cuts by Ice Cube and Liz Phair makes sense. A power-tool-in-your-ear contribution by Rage Against the Machine (''Year of the Boomerang'') is strong enough to nearly erase the memory of Tori Amos' hysterical, deeply off version of R.E.M.'s ''Losing My Religion,'' on which she sounds like she's auditioning for a soap-opera role.
