Hoboken, N.J., trio YO LA TENGO is something of a critic's darling, thanks to light, charming and eclectic tunes marked by excellent songwriting and musicianship. Last year's I Am Not Afraid of You and I Will Beat Your Ass marked a return to form after the neutered Summer Sun, and rock fans know it's important to see a band when it's having a good year, right? The group visits the Variety Playhouse on Sat., FEB. 3, and you should be there or, uh, they'll beat your ass. $20. 8:30 p.m. 1099 Euclid Ave. 404-524-7354. www.variety-playhouse.com.
