During the period 1979 until her death, Polsky was talent buyer at Hurrah and then Danceteria in New York, also promoting shows at The Ritz and booking bands out across the U.S. In this role, she was crucial in breaking many, particularly UK-based, post-punk acts in the U.S., including tours for The Smiths, New Order, Einstürzende Neubauten, The Only Ones, The Sisters of Mercy, The Birthday Party, Cocteau Twins, and The Chameleons. She worked closely with Shirley O'Loughlin at Rough Trade to bring in The Raincoats, Delta 5, Young Marble Giants, Cabaret Voltaire, The Go-Betweens, The Slits and The Pop Group for their U.S. debuts. Ruth booked the Joy Division USA tour in May 1980, which was canceled after Ian Curtis' death. Other bands that got their first break in the U.S. via Polsky are The Cult, A Certain Ratio, Echo & the Bunnymen, Simple Minds, The Teardrop Explodes, Red Lorry Yellow Lorry, Gene Loves Jezebel, and the Jesus & Mary Chain.
