Tony Bennett's new 'Duets II' album -- including duets with Carrie Underwood, Faith Hill and Willie Nelson -- is now streaming at NPR, with the exception of his work with Lady Gaga. It's the first chance to hear Hill join Bennett on 'The Way You Look Tonight' and Nelson on 'On the Sunny Side of the Street.'

Last week fans got a glimpse at the 85-year-old legend's work with Underwood. The two showed off great chemistry on 'It Had to Be You.' Like that collaboration, both Hill and Nelson's songs with Bennett are the furthest thing from country. Tender piano and delicate acoustic string instruments replace the slide guitar and fiddles their fans are used to. All three artists show a great range and tender touch in a genre they don't regularly work in.

'Duets II' is in stores on September 20. Other artists included on the project include Mariah Carey, John Mayer and Amy Winehouse. Last Wednesday, Bennett appeared on the finale of NBC's 'America's Got Talent' to sing with Queen Latifah.
