The strongest album of Baez"s post-folk career found the singer-songwriter baring her soul about a number of issues in her personal life (both Diamonds & Rust and Winds of the Old Days are about her relationship with Bob Dylan) and also covering songs by her contemporaries. Highlights include her versions of the Allman Brothers" Blue Sky ; Jackson Browne"s Fountain of Sorrow ; John Prine"s Hello in There , and her duet with Joni Mitchell on Dida .
