[1] The ranch hosted some of the most prominent acts of the 1970s and 80s and was closely associated with the band Chicago, who recorded five consecutive albums there between 1973 and 1977.
Szymczyk knew Guercio was building a new studio, visited the in-progress barn conversion at the ranch, and concluded that it would work for their project.
Szymczyk next made Rick Derringer's All American Boy and the hit single "Rock & Roll, Hoochie Koo" there.
He also recorded his next two albums, Captain Fantastic and the Brown Dirt Cowboy and Rock of the Westies at Caribou Ranch.
Simultaneously in 1974 The Beach Boys attempted to record new material for their first studio album since Holland two years prior.
Beach Boys members Carl Wilson and Bruce Johnston sang backing vocals in support of Elton John's "Don't Let the Sun Go Down on Me" during this time.
In 1978, Guercio co-owned a club in the North American Soccer League called the Colorado Caribous, which played their home games in Mile High Stadium in Denver.
