Once you have heard singer and guitarist Billy Ruegger live, it’s easy to see why he is quickly establishing himself as a must hear performer in his home state of Connecticut. It is not just his command of the guitar, by which he earned his undergraduate degree from the New School for Jazz and the opportunity to be guitarist of nationally touring reggae group Mystic Bowie’s Talking Dreads, nor is it his warm voice reminiscent of James Taylor’s. It is that in each and every performance, whether he is delivering convincing renditions of fellow Fairfield native John Mayer’s music at a sold out show at The Acoustic or playing solo at Shearwater Coffee Bar on a Sunday morning, Billy immerses himself in the music so completely that listeners can’t help but be taken in with him.
