Circadian Rhythms are the type of group that raise the joy factor in the air. With cascading well-rounded tunes that sprinkle in strolling pieces of keys, xylophone, horns, etc. and marrying them with enriching ensemble harmonies, the band carves out a place that recognizes the past, but still works in the present. It’s casual comfort that opens the doors wide open without losing focus in the process. Tonight at Johnny Brenda’s, they’ll have copies of their latest EP A Passing Thought and new tunes to share. Circadian Rhythms will be joined by the folky, Americana Nashville outfit Great Peacock, who has also a new record, Making Ghosts, due out May 12. Fellow Nashville natives The Apache Relay headline, knitting together ironed-vocals stretched out over a large rootsy field. Johnny Brenda’s, 1201 N. Frankford Ave., 9pm, $12, 21+ – Michael Colavita
