For most of us, being serenaded is a rare occurrence. It’s even more uncommon when it involves an accordion. So, when the Bowerbirds flutter into town, treat the occasion with special glee - the kind usually reserved for Halley’s Comet or a leap year. The North Carolina-based band creates gentle waves of songs, dealing with its fascination with the Earth’s sacredness and love through ornately crafted lyrics and sweet, careful folk. Bowerbirds has a rotating cast of musicians, but Beth Tacular (accordion, keys) and Phil Moore (guitar) are its mainstays. Matt Damron is playing drums on tour, as Bowerbirds test out songs from its upcoming album, Upper Air. Songs from Air are spacious soundscapes that seem to draw on artists Bowerbirds have recently toured with – Bon Iver and John Vanderslice. “Northern Lights” is a good example of what Bowerbirds do best; while Tacular’s sprightly piano twinkles, Moore’s swinging guitar rocks back and forth, and his vocals caress with the oozing romanticism of “all I want is your eyes, in the morning as we wake, for a short while.” Megafaun and Craig Ramsey & The Nice People open at 9 p.m. at the Beachland Tavern (15711 Waterloo Rd., 216.383.1124). Tickets: $8 advance, $10 day of show.
