The latest in the SoundCheck series of streaming shows from opera house continues with a performance from the midcoast duo. With a sound that traverses Americana, folk, rock, blues and R&B, it should prove to be a satisfying night of music. You’ll likely hear tunes from their 2016 EP “House of Dreams” and their 2009 album “Here You Are.” Should you miss the free livestream, it will be archived on the venue’s Facebook page and YouTube channel indefinitely.
