Before she became the omnipresent babe at grizzled-rock-star reunions, Sheryl Crow was a Missouri gal with a big voice, a mutable country-rock countenance and a lust for pop hooks. The loping "Leaving Las Vegas" launched her eclectic Grammy-sweeping 1993 debut, which also had L.A. folk funk, piano-bar blues, even a Dylan-cum-R.E.M. "rap" ("The Na-Na Song"). The bonus disc doesn't exhume her never-released 1992 album (try the Internet), but it has worthy takes on Eric Carmen's 1975 power ballad "All by Myself" and Led Zep's "D'yer Mak'er" — bold strokes from a singer swingin' for the bleachers.
