The band shared the sad news yesterday (23 March) via their Facebook page, "Our hearts are broken and heavy with the news that our brother Tres has passed away. Tres was a lover of music--his soul was made of it and he poured that into all he did with such heart and passion."

Psychic Ills add, "We will forever be changed by knowing him and the empty space his leaving has left behind will never be filled. We want to thank you all for the love and support that you have given us through the years. We love u T and will miss you every day."

Warren fronted the psych-rock group since their formation in 2003. Their last album was 2016's Inner Journey Out, which featured Hope Sandoval collaboration "I Don't Mind".
