LOS ANGELES (AP) — Steve Aoki is undergoing surgery to repair his vocal cords.

The 37-year-old electronic music artist says in a video posted Thursday on Facebook that he’s canceling five performances in Europe for the operation and recovery.

Aoki says in the video that he “severely messed up” his vocal cords by screaming at his shows for the past 20 years. He also showed images of his damaged vocal cords.

The disc jockey is a prolific presence on the electronic dance music scene and has collaborated with the likes of will.i.am, LMFAO, Iggy Azalea and Lil Jon.

Aoki is canceling performances in Ibiza, Spain; Wijchen, Netherlands; and Newcastle and Upminster, United Kingdom.
