Bob Vylan's career may be in trouble following their controversial performance at Glastonbury, experts tell Newsweek. Over the weekend, the English punk rap duo sparked outrage at the music festival in the United Kingdom. During their set, they led crowds in a chant of "death, death to the IDF," referring to the Israeli Defense Forces.

The prime minister is involved; so is the U.S. deputy secretary of State. The BBC is changing policies. But Bob Vylan remains steadfast.

The rap duo were set to headline a Manchester music festival and play Kave Fest in France, but will no longer be appearing following the fallout from their Glastonbury set.
