Formed in Chicago in the late 1960s, the Kaldirons recorded one single on the Twinight label. They later renamed themselves the Final Solution and recorded an entire soundtrack for BROTHERMAN, a Blaxploitation film scheduled for 1975, but later shelved. The entire soundtrack was privately held by band guitarist, arranger, and songwriter Carl Wolfolk until Numero Records in Chicago licensed it for release for the first time in 2008.
