Robert Sarazin Blake sings non-traditional holiday tunes at the Green Frog

Here’s what James Hardesty, proprietor of the Green Frog, says about guitarist and songwriter Robert Sarazin Blake: “He never performs the same show twice. With his unrelenting output of songs over the years, as well as a deep love of improvised banter, you never know exactly what you are going to get.”

Blake performs his annual holiday show from 6 to 9 p.m. Tuesday, Dec. 23, at the Frog, 1015 N. State St., and, as Hardesty says, “going in whatever direction he might take them leaves the listener with the feeling that something special just happened. Blake tends to find obscure holiday songs that are not of the ‘Muzak’ ilk, following no predetermined course.”

Because usually, he does not.
