ozens of fans left a festival in London mid way through a set from US band The Strokes.
The voice of frontman Julian Casablancas was difficult to make out as he sang and spoke to the crowds at All Points East in Victoria Park late on Friday evening.
Casablancas, 45, was wearing sunglasses and a waistcoat at the opening of the show as he appeared to suffer with vocal issues.
Songs were at various points difficult to make out but Juicebox, Reptilia, Under Control, Red Light and Last Nite were heard as a light display cast geometric shapes and a radar pattern onto the stage.
The band could be heard playing instruments, but large groups of fans appeared to leave the festival early shortly after the set began and before The Strokes had finished.
Crowds at the festival also heard sets from artists including the Yeah Yeah Yeahs, Girl in Red and Angel Olsen at All Points East on Friday.There were no sound issues reported with other bands during the rest of the day.
Representatives for The Strokes have been contacted for comment.
