Glowberon: Johnny Blazes and Brian King at 8 p.m. Friday at Oberon, 2 Arrow St., Harvard Square. Tickets are $25.

Born exactly 10 years apart, Johnny Blazes and Brian King are twin queens of song and glitter exploring intersections and spaces between their versions of queerdom, interlacing story, song and video to expose the gaps imposed not only in generation, but by geography, gender … and shoe size. Information is here.

Art exhibits and receptions: “Death & Technicolor” from noon to 2 p.m. Saturday at Somerville Community Access Television studios, 90 Union Square, Somerville; and “M/othering,” from 6 to 9 p.m. Saturday at Gallery 263, 263 Pearl St., Cambridgeport. Both free.

Inspired by the big questions of life after death, parallel universes, urban decay, time, dimensions and the unknown, and wielding mainly the exploratory tools of acrylic and watercolor, Becky Carpenter attempts to capture a whimsical sense of the eerie in her “Death & Technicolor” series, hanging in Somerville through January. “M/othering” is more down to earth, as artists Fletcher Boote, Maya Pindyck, Tereza Swanda and Angela Rose Voulgarelis look at motherhood, childhood, family relationships, cultural identity and positions of privilege in a range of media, driven by questions about inheritance and systems: What continuity is there, if any, between generations? What gets handed down from mother to child? What gets passed from nation to education, or from education to family structure? What images and stereotypes of mothering tend to spread and reproduce? The reception is from 6 to 8 p.m., followed by an hour of more formal Artist Talk. “M/othering” is up through Feb. 4.

Laughing Liberally from 8 to 9:30 p.m. Saturday at The Center for Arts at the Armory, 191 Highland Ave., Somerville at The Center for Arts at the Armory, 191 Highland Ave., Somerville. Tickets are $8.

An array of comedians and storytellers push their liberal agenda, including suave gentleman comic Scott Oddo, electrifying Chicago native storyteller Ken Green, whimsically dark and funny avant-garde musician, comedian and storyteller Angela Sawyer, New York’s Brandon Collins and headliner Sam Ike. Proceeds from the night will be donated to the ACLU, which will have a representative on hand as special guest. Food and drink is available, and parking is free. Information is here.
