Recently Everlast, the Roots and Public Enemy lit up the Trocadero Theatre in Philly to raise money to help pay the heating bills of low-income and elderly Americans. The third annual Artists for Heat, organized by local entertainment company 3Kingdoms, was a huge success — and some local public school students got a chance to get involved. Six million Americans will go without heat this winter, and approximately 300,000 are at risk of losing heating service in Philadelphia alone.
