UPDATE: The band has now shared their statement on his passing and you can read it below. 

Sad news as legendary Death Metal vocalist and co-founder of At The Gates, Tomas Lindberg, has died. He was just 52. The news comes via Swedish broadcaster SVT. Last month, Lindberg revealed that he had been battling adenoid cystic carcinoma (ACC) — a rare type of cancer that typically arises from the salivary glands — for roughly 18 months. The band completed their latest album just after Lindberg revealed his diagnosis. Lindberg co-founded At the Gates in 1990. He was also a member of The Crown, Disfear, Lock-Up, and The Great Deceiver, among others. RIP.

Tomas passed away this morning following complications related to his ongoing cancer treatment.
Despite intensive medical efforts, his life could not be saved.
Tomas – You were an inspiration to us all. A true friend, both compassionate & sympathetic. You will always be remembered for your generosity and your creative spirit.
You will be eternally missed.
Forever in our hearts.
