Two drummers suffered non life-threatening injuries, and were taken to a local hospital.
The Star reports it happened east of the town of Lee's Summit on U.S. 50.
Authorities say according to an initial investigation, the bus apparently tried to turn into a median and hit the semi.
The bus, which belonged to the band Potcheen, had five people onboard.
Terri Worthington, who identified herself as the mother of one of the people onboard the bus, says the driver and owner of the bus was Potcheen's drummer, Christian Blochinger. She says he was "badly hurt" and remained hospitalized on Wednesday.
Worthington says Blochinger was driving another Denver-based band, Savage Henry, on its Midwest tour. The drummer of Savage Henry, Michael Boyd, suffered a concussion in the crash and has since been released from a local hospital, according to Worthington. On Wednesday he had some bruises, but was otherwise in good spirits, she added.
Savage Henry played a show at the Midwest Music Showcase at Jerry's Bait Shop, located at 302 SW Main St. in Lee's Summit the night before the crash. They were scheduled to play a show at Knickerbockers at 901 O St. in Lincoln, Neb. on Wednesday and at Herman's Hideaway, located at 1578 S. Broadway in Denver on Friday.
Friday's show at Herman's Hideaway is part of the venue's "Almost Famous" series, sponsored by Alice 105.9.
Worthington says Savage Henry has had to cancel their appearances at both shows due to Boyd's injuries and because the band's instruments were still on the totaled bus, which was in an impound lot pending investigation. She says the band will reschedule its show at Herman's Hideaway soon.
It was not clear whether the band's instruments survived the crash. Worthington says three of Savage Henry's band members will fly back to Denver on Wednesday, while two others plan to stay behind, waiting until local law enforcement allows them into the impound lot to retrieve their instruments.
Savage Henry is a rock/alternative/pop band set to release its album "Step Lively" in the spring.
Potcheen bills itself as "Colorado's premiere Celtic Pirate-Punk-Folk-Rock band."
