Wikipedia's disambiguation reveals that there are Kurdish, Senegalese and Japanese singers named Issa. But this one's Canadian; she adopted the name three years ago while traveling, shortly after selling her house and giving away most of her possessions. She used to be called Jane Siberry. Back in the '80s and early '90s she enjoyed ample critical respect and some sizable underground arty folk-pop hits. Since then she's withdrawn ever outward into the fringes, but her recent work, which waxes by turns biblical, personal and geo-political, doesn't stray too terribly far from the jazzy, sentimental/experimental Laurie Anderson-meets-Joni Mitchell vein she was mining 15 years ago.
