Lyle Brewer’s solo guitar album “Juno” is the result of two things: the snowstorms that consumed Boston in the early months of 2015 and the sobriety that saved his life. “Juno,” which made the Boston Globe’s list of Best Local Albums of 2015, “showcases the cool sophistication of his guitar playing, not to mention his evolution as a songwriter” (Boston Globe). The first blizzard of the season hit Boston on January 27, 2015 andshut down the city for three days. That blizzard, “Juno,” lent its name to the title track. Every storm that winter, Brewer wrote a song.
