BAKKEN TRIO Sunday: The Bakken Trio is in its fourth decade, and a note of nostalgia seems to have crept into the group's publicity for its season opener, titled "Reflections on Ghosts and Tides." But one can have no reservations regarding the program: Beethoven's "Ghost" Trio, Dvorak's Op. 87 Piano Quartet (with violist Ken Freed) and the jazz-influenced "Between Tides," a 1995 piano trio by the now-underplayed Toru Takemitsu. (4 p.m. Sun. $15-$25. Antonello Hall, MacPhail Center for Music, 501 S. 2nd St., Mpls. 612-374-3175 or bakkentrio.org.)
