The U.S. State Department has revoked visas for the British rap duo Bob Vylan following their controversial performance at the Glastonbury Festival, where they chanted death to the IDF. The duo, known for blending punk-rock and hip-hop, was scheduled to open for American artist grandson on a U.S. tour in October and November. Their provocative act sparked outrage and led to the visa cancellation, highlighting the ongoing tensions around freedom of expression and political statements in live performances.
