Sunday

Quentin Callewaert (via Instagram).

Quentin Callewaert and Honest Mechanik perform from 2 to 5 p.m. Palmer Street, Harvard Square. Free. Callewaert, who starts this bill, is a 21-year-old classically trained acoustic guitarist and singer who blends Americana, gospel and bluegrass. Honest Mechanik is the indie-pop duo of Susan Cattaneo and Paul Hansen (The Grownup Noise), which starts at 4 p.m. with “quirky lyrics and ear-worm melodies” and “the vibe of The Velvet Underground paired with the intimacy of Belle and Sebastian.” Part of the Cambridge Plays series. Information is here.

Campfire. Festival from 4 to 11 p.m. today and Monday at Passim, 47 Palmer St., Harvard Square. Tickets are $10 for daily passes or $25 for a weekend pass (or free to stream). Passim’s twice-a-year homegrown festival of Americana, bluegrass, blues, Celtic, country, folk and related musical styles runs throughout the long Memorial Day weekend with 26 hours of live music from 49 acts. Originally just a way to fill a bad booking weekend in 1998, the festival now competes with the rock- and pop-focused Boston Calling across the river. The distressingly punctuated Campfire. aims to develop talent and celebrate the local music scene, with organizers saying shows can blur the line between performer and audience member – just like might happen sitting around an actual campfire, strumming a guitar or two. Information is here for the all-ages festival, now in its 24th year. 


Monday

Lidiya Yankovskaya conducts the Refugee Orchestra Project in 2016 (via Facebook).

Memorial Day Observance with the Refugee Orchestra Project from 10 a.m. to 5 p.m. on Cambridge Common, near Harvard Square. A concert to benefit victims of the Ukrainian refugee crisis is a highlight to this daylong event. The nonprofit Refugee Orchestra Project, under the musical direction of founder Lidiya Yankovskaya, plays selections from 11:30 a.m. to 1 p.m. that include works by Ukrainian composers and a rendition of the Ukrainian national anthem, with donations going to a Relief Fund for Ukrainian Musicians from cities such as Mariupol, Kharkiv, Chernihiv and Severodonetsk. The day begins with the project and a Ukrainian choir accompanying a Memorial Day observance; there will also be marching regiments and bands parading past the review audience on the main lawn. After the concert comes a Prince Hall Masons procession and wreath-laying, and finally musical entertainment from the husband-and-wife Team Ragoza of Springfield. More family fun is by the Kemp Playground, and food trucks will be on hand. Veterans eat free on a first-come, first-served basis. Information is here.
