His locks may not be as free-flowing, and actress Linda Evans is no longer at his side, but Yanni still has that contemporary-classical instrumental thing all sewn up. Touring on last year’s No. 1 New Age album, Truth of Touch, the world-famous pianist performs at 7:30 p.m. tonight at Civic Center Music Hall, 201 N. Walker. Tickets are $45-$125.
