If their release history is any guide, best savor Tezukayama (Strange Daisy), the weird, wondrous new album by A Living Soundtrack — it might be a while before you get another one. Fans of the New Orleans instrumental band waited five long years for the full-length follow-up to 2006's EP. It's now been almost seven years since debut LP How to Grow a City. (Answer: patiently.) That first record — a curious introduction to the band's meticulously arranged synths, samples and loops — could be the living soundtrack to a benevolent extraterrestrial encounter or a Honey, I Shrunk the Kids-vantage garden party attended by oversized, antennae-tickling insect guests. (The playful perspective-shifting and organically sprouting song structures extend to the titles: "Germination," "The Consolidation of Exponential Growth.") The giant bugs came back for How to Grow a City — in spirit on the grasshopper-sawing, theremin-esque opener "Good Morning, Dhrangadhra," and in carapace on 8-bit ice-climber "Insects Are the Mathematicians of Nature" — but this time they were pawns in an expansive, arithmetic digital/analog program, cast in "Video Game, the Movie" and tasked with mapping the "Dodecahedron." The final song on that album is called "A Nap of Indeterminate Length" (now known to be 81 months). Tezukayama is drawn from Japan and deals directly with a near-fatal car accident suffered in Thailand by songwriter Matt Aguiluz. (Second track "Wijarn Pongpanich" is the name of the surgeon who saved his life.) Its unwritten lyrics might be to enjoy this while you can — no telling how long the next nap may be. AF THE NAYSAYER (another mathematician of nature), BLK and Shuvuuia open. Tickets $10. At 10 p.m. Saturday. Gasa Gasa, 4920 Freret St., (504) 338-3567; www.gasagasa.com.
