The Baltimore Classical Guitar Society wraps up its 20th anniversary season on Saturday with a concert featuring Manuel Barrueco, viewed by many as the finest guitar artist of the day, and the top-notch Cuarteto Latinoamericano. The program includes the premiere of work written for the occasion by Gabriela Lena Frank, who will discuss the composition during a pre-concert presentation. Baltimore has become a classical guitar center over the years, largely due to Barrueco, who is on the faculty at the Peabody Conservatory, and the Society has been doing admirable work at keeping the spotlight on the subtle, sensual pleasure of the classical guitar. This anniversary season finale promises to be a colorful night.

The concert is at 8 p.m. Saturday (the chat with the composer is at 7:15 p.m.) at Peabody's Friedberg Hall, 17 E. Mount Vernon Place. Tickets are $35 ($30 for students, seniors and Baltimore Classical Guitar Society members). Call 410-247-5320 or go to bcgs.org.
