The fourth in our series of acoustic guitar summits showcases both new and established talents in Los Angeles. Mark Goldenberg has played in bands with Al Stewart, Jackson Browne, the Pointer Sisters, Linda Ronstadt, and many others. His solo work is meditative and expressive, with elements of Latin jazz and Americana. Bluegrass-influenced Cameron Knowler is no stranger to our stage, having performed at Collage three times before, and this appearance follows a two month tour in Europe just before he heads for a residency in Nashville. Barry Johnson is a relative newcomer, an emerging artist who has released a critically acclaimed album with original songs and instrumentals. They will perform individually before the group improvisation that is the finale for these shows.
