A Sunny Day in Glasgow released their first album in four years, the Jeff Zeigler-produced Sea Went Absent, earlier this week via Lefse Records, and this evening, they’ll headline a triad of local artists that know how to push the envelope. The six-piece develops an ethereal state of affairs, capturing soft siren-esque vocals combined with floating layers of instrumentation, pieces of keys/synth, strings percussion, guitar etc., fitting them together to form a beautiful musical portrait that somehow slightly drifts out there yet, for the most part, remains within reach. On a similar note, the experimental-pop pairing of Andrew Thiboldeaux and Chris Ward, a.k.a. Pattern is Movement, delivers its intricately groovy, multi-instrumental R&B, fusing a variety of musical textures while the end product appears seamless. Myrrias a newly formed quartet, which includes Mikele Edwards (Arc in Round), Amy Harkanson (Downtown Club), Casey Bell (Break It Up), and Emily Robb (Lantern), opens the show weaving together vocals with a darker edge, industrial instrumental tone.
