The BBC said Friday 24-year-old Stephen Fitzpatrick, 25-year-old Audun Laading and their tour manager, 37-year-old Trevor Engelbrektson, were among the four people killed in the fiery crash near Centennial along Interstate 10.
Fitzpatrick and Laading made up the Liverpool-based music group Her’s.
The group was reportedly traveling to California while on a tour across the United States.
A post on the Her’s Facebook page on Monday read: “US tour has gone swimmingly so far...Got a hot sunset date with the Grand Canyon tonight.”
Her’s played a show at The Rebel Lounge on Tuesday night, according to a list of concerts from their website.
A sold-out show was scheduled for Wednesday night in Santa Ana, California. Their last American show on the tour was scheduled for Thursday in San Diego.
Fans have been posting messages of sympathy on their recent Facebook posts and YouTube videos.
The Arizona Department of Public Safety confirmed the identity of the victims in the crash on Friday morning.
DPS told ABC15 Thursday, “information will be extremely delayed due to almost all evidence being lost in the fire. The bodies are not identifiable and we are relying on the (Medical Examiner’s) office to help with positive ID.”
DPS said Engelbrektson was driving the passenger van with Fitzpatrick and Laading as passengers. The driver of the Nissan pick-up truck was identified as 64-year-old Francisco Edward Rebollar of California.
All four people were pronounced dead after the crash Wednesday morning around 1 a.m. near milepost 68.
