The Friends of the Berkshire Athenaeum will present Ken Bonfield’s Artistry of the Guitar, a solo concert, at 2 p.m. Saturday, April 5, at the Berkshire Athenaeum, 1 Wendell Ave. The concert is free.

With 20 years of experience as a full time musician, Bonfield focuses on composing and performing original instrumental pieces.

The concert will be performed on guitars of his own design, commissioned from master luthier Alan Carruth. In addition to playing a standard six string, two baritone guitars, and an 11 string harp guitar, Bonfield will discuss advances in guitar design, technology, and playing styles in the last 140 years.
