A Reggae label. One of Dennis Harris's stable of labels, along with Dip, Eve, Lucky, etc, Serious Business released at least three singles in 1977-78. Numbering was in an SB-00 series and reached SB-05, but a couple of the numbers seem not to have been used. For some reason the label looked almost exactly the same as the green-and-red version of Atlantic.
