DYNAMIC DUO

Johnny and June, George and Tammy, and . . . Peter and Victoria?

Sounds incongruous, perhaps, but the folk ‘n’ roll songs performed together by Peter Case and Victoria Williams in otherwise separate sets Friday at McCabe’s again served warning that this dynamic duo has what it takes to become one of the more endearing and enduring husband-and-wife teams in popular music. Alike enough to blend with each other, they are also eccentric enough to complement each other.

Case sounds like a less self-centered John Lennon, either solemnly spinning very literal short stories or drifting toward a more mystical view of love than in his Plimsouls days. Williams’ sounds like a louder, loose-limbed, Louisiana-bred Rickie Lee Jones, happily warbling about shoes, bums, motels, nature and man’s inhumanity to fish. Together, crooning T-Bone Burnett’s “The Power of Love” or Porter Wagoner’s “I Dreamed I Saw America On Her Knees,” they’re really something.
