Attrell Cordes, better known as one half of the seminal 90s R&B/hip-hop group P.M. Dawn, has passed away today from renal kidney disease at the age of 46, TMZ reports. Cordes, along with his brother Jarret, formed P.M. Dawn in New Jersey in 1988 and went on to become known for their 1991 No. 1 hit "Set Adrift on Memory Bliss." A post written on the group's Facebook page read, "My Heart is at Peace B-Cuz U suffered so long."
