These two acts are sharing top billing on this tour to celebrate recent releases from both. Lights, an expressive Canadian alt-rock vocalist and songwriter, put out Little Machines last year to widespread acclaim. Meanwhile, Los Angeles indie rockers the Mowgli's are promoting this year's Kids in Love. These acts also share an upbeat-yet-contemplative sound that tends to inspire peaceful contentment rather than raucous joy. Tue 7 p.m.
