The waves of synths and modulated keys that mark the musical wanderings of L.A. electro-pop songwriter Pat Grossi, working under the name Active Child, have been steadily growing in depth since the project’s debut in 2011. On his latest release, Mercy, Grossi’s Active Child matures into a project that deftly combines groovy, danceable beats and emotionally edgy lyrics. Currently touring the country, Active Child comes to the North Bay for an intimate evening that includes an opening set from chill Icelandic trio Low Roar on Thursday, July 2, at City Winery Napa, 1030 Main St., Napa. 8pm. $15-$22. 707.260.1600.
