"Redbud Tree," a highlight of Mark Knopfler's eighth solo album, could've been written 100 years ago. But given our ecocrisis, this tree-hugging folk gem, embossed with a shimmering fingerpicked Strat, feels cannily modern. Knopfler's sueded voice has changed little since his 1980s heyday, and his elegant electric-guitar work sounds better than ever. The 20 songs, most top-shelf, are a textbook of folk styles, from Irish ballads ("Kingdom of Gold") and country-flavored weepers ("Seattle") to slide-driven blues ("Don't Forget Your Hat") and Tin Pan Alley nostalgia ("Radio City Serenade"). On the title track, he shows offhis acoustic playing, a folk-rock vet returning to the source.

“All Along the Watchtower”

Jimi Hendrix got hold of Bob Dylan's early John Wesley Harding tapes and in late 1967 recorded a version of "All Along the Watchtower" with the Experience in London. Dissatisfied with that first development, Hendrix brought those tapes with him to New York in early 1968 when he began work on Electric Ladyland. Eddie Kramer, Hendrix's engineer at the time, told Rolling Stone that Hendrix "was still looked upon by his basically white audience as the mammoth black guitar hero. There was a constant fight within him to expand himself." Hendrix's successful take on Dylan's work has long been recognized by the songwriter. "I liked Jimi Hendrix's record of this and ever since he died I've been doing it that way," Dylan wrote in the liner notes to his Biograph box set. "Strange how when I sing it, I always feel it's a tribute to him in some kind of way."
