Former YNGWIE MALMSTEEN keyboardist MATS OLAUSSON has been found dead in a hotel room in Rayong, Thailand. He was 54. His body is reported to have been discovered among empty whisky bottles and beer cans.

He'd been staying in the hotel for a week, but an employee said he hadn't paid for his room and hadn't taken meals since his arrival. The musician is believed to have died in the 24 hours preceding his body's discovery.

OLAUSSON joined MALMSTEEN for his fifth album, 1990's Eclipse, and remained until 2000's War To End All Wars. He appeared on a total of 70 albums and also performed with Kamelot, Iron Mask, Nemo, Geff, Ark and others.
