Musician Joshua Webb was killed in a car accident in Atlanta, Georgia on Wednesday (09May12), aged 27.
The star, who appeared on R&B singer Ledisi's Grammy-nominated album Pieces of Me, was driving with his cousin to pick up his new car when their vehicle collided with a tractor trailer.
Webb was pronounced dead at the scene while his relative was hospitalised with a broken leg and spinal cord injury, according to a publication in the star's native Missouri, St. Louis Today.
Ledisi has taken to her Twitter.com account to pay tribute to her former collaborator, writing, "When u hear the piano part on (my track) Bravo that's Josh Webb R.I.P My love & prayers 2 The Webb Family... So grateful for so much.. I met and I am around so many of God's angels."
The tragic artist featured on Ledisi's songs Bravo and Shine and he was also the brother of John Webb, Jr., aka Jon Jon Traxx, who's produced a slew of hit tunes for Beyonce, Usher and Mary J. Blige.
Many ticket-holders couldn't get into the O2 Arena show on Tuesday night (September 19th) because they didn't bring photo ID to match their booking.
An album re-release, a new song and a documentary mark the singer's legacy this year.
The film will be the first in the Marvel Cinematic Universe led by a person of colour.
The actor plays the titular hero in the forthcoming adaptation.
