Rock

Judy Collins and Livingston Taylor. Liv is higher-pitched than his brother, though fortunately not as high-strung. He can be seen frequently at the People's Bank--Coolidge--standing in line like one of the, um, people, although a discreet peek at the blue paper in his skinny hand reveals that he may be closer to the corpulent and feline species. Anyway, he banks there, and his concerts are really pleasant--he's charming, sings funny songs, and has a good amateurish style. And his feel for the North Carolina whence the Taylors come (oh, alright, Chapel Hill) is better and earthier than his brother's, more into folklore and less into his navel. Judy Colline, who is appearing with him tonight at Lenox (7:30, tickets at Ticketron from $5.50 to $7:50), does a bang-up version of Dylan's "Daddy You've Been On My Mind," but her voice lamentably sounds like Lark cigarettes taste--sweet and syrupy And staler all the time.
