The former Pro Shop at Arroyo Seco Golf Course sat empty for years before Brad Colerick's long-running Wine & Song concert series found a home there in 2015. A few patrons made donations to buy a stage, curtains, tables, chairs, and a mixing board. Dinosaur Farm owner and Wine & Song house band member, David Plenn, donated a small blue neon guitar sign which Colerick hung in the window to indicate live music was happening. It was soon dubbed "The Blue Guitar room" by Kathryn Compton, who was organizing a fundraiser in the space for the 2016 Eclectic Music Festival.

Before long, a Thursday Jazz at the Blue Guitar show was added. Eager music fans would frequently pack the room on Wednesday and Thursday nights to hear great live music. The Blue Guitar room has gained a reputation as one of the finest intimate listening room venues in the Los Angeles area. It has become a mandatory stop for many touring jazz and Americana artists coming through the LA area. In 2017, Michelle Hammond of Munch Company made a donation for a larger custom neon window sign. Concert goers from all over the region have discovered South Pasadena and its beautiful shops and restaurants as a result of coming to shows in the arroyo.
