The way I see it, Mos was just taking advantage of the ready made crowd at the MTV VMA's. His impromptu "Katrina clap" performance may not have been planned but it was relevent and I have to respect his gangsta. Just picture it... I bunch of teeny bopping MTVers crowded outside Radio City Music Hall ready to worship the overpaid and undertalented "artists" (few exceptions) when along comes Mos Def, bearer of bad news, to remind them all, that while they excessively celebrate all that is great with materialism and mainstream music, there are folks in New Orleans who are still homeless a year later. What a party pooper.
