In 1970, the concords folded and isaacs struggled on alone. His initial self-productions were similarly unsuccessful, while further cuts with edwards did no better. regardless of this poor track record, in 1973 isaacs set up his own record store and label, African museum, in partnership with Errol Dunkley, a young singer with a string of hits to his own name. Apparently some of Dunkleys own magic wore off and one of the label's first releases, Isaacs' own self-produced "My Only Lover" was an immediate hit and the floodgates opened wide. besides African museums' offerings, Isaacs helped keep the label solvent by recording with virtually every producer on the island for a stream of hits that showed no sign of abating. between 1973 and 1976 alone, the singer released more material than most artists do in a lifetime, virtually all of it timeless classics. the cool ruler he remains.
