Meagan Grandall has always defined her dream-pop music project, Lemolo, as a two-person thing: Just Grandall singing and playing guitar and keyboards, and a drummer.

Dec. 2, though, Grandall and drummer Adrian Centoni will have lots of backing for a concert at Abbey Arts at St. Mark’s Cathedral, 1245 10th Ave. E. in Seattle. The two will be backed by what Grandall describes as “a string ensemble and other orchestral elements” in an 8 p.m. show (doors open at 7) that also will feature Portland’s Loch Lomond and Seattle electronic duo NAVVI.

Orchestral arrangements for Lemolo’s set were supplied by Alex Guy of the band Led to Sea.

Tickets are on sale through Brown Paper Tickets, 800-838-3006, brownpapertickets.com, priced at $15 advance, $20 day of show and $13 student.

The concert is part of a series being produced by Abbey Arts at the historic cathedral. Lemolo’s show will be followed on Dec. 3 by Damian Jurado.
