A few years back, R.E.M. guitarist Peter Buck and bassist Mike Mills formed the Baseball Project, a band that serves as a "musical tribute" to our national pastime. The group also includes Steve Wynn of the Dream Syndicate and Steve Wynn & the Miracle 3, and drummer Linda Pitmon. The side project has flourished: It has released three proper albums as well as a live EP and a 45 single. Starting today, the band will hold down a residency at the Rock Hall during All-Star Week. Performances take place from noon to 2 p.m. today on the Klipsch Audio Stage; additional shows are set for 1 to 1:45 p.m. tomorrow, and from 3 to 3:45 p.m. on Tuesday, outdoors on the Rock Hall's plaza. Admission is free. (Niesel)
