To understand what a Dylan deep cut sounds like, look no further than “The Groom's Still Waiting at the Altar”. Is it a raucous, soulful slab ripped from his Highway 61 electric period? Nope. It's a little-known b-side from the not-exactly-well-received 1981 gospel record Shot of Love—still packing the swagger and scorn of a Blonde on Blonde-era masterpiece. “Brownsville Girl” finds one of America's greatest lyricists hooking up with one of America's greatest playwrights—Sam Shepard—for a gently swaying 11-minute epic story that's as heartfelt and evocative is as it funny and playful.
