Why did the band leave Detroit?

The band Black Flag left Detroit as part of a tour that ended with two nights at Greystone. According to Henry Rollins, Greg Ginn, the band's leader, decided to take a year off to reinvent their label, SST. This decision was surprising to Rollins, who couldn't fathom such a long break from the band's intense lifestyle. While visiting the East Coast, Rollins received a call from Ginn, who stated that he had quit the band. This abrupt end left Rollins feeling disoriented and led him to pursue other opportunities like acting and creating his first solo record 1.
