A new post on Bandcamp Daily covers "The Cottage Industry of Indie Game Soundtracks" (thanks nin). This offers a history lesson on the topic, a lot of interesting detail on how this aspect of indie gaming has grown so large, and profiles of several artists who have made game soundtracks their lives. And though things have grown, the article also reflects how this remains a niche in the music industry:

But on the artful edge of indie gaming, where Guthrie has found a niche, music is often indispensable. The musicians who specialize in soundtracking some of the medium’s most groundbreaking titles have gained cult followings, and some are becoming full-blown stars. On Bandcamp, soundtracks for games like Undertale and webcomics like Homestuck, have remained near the top of the sales charts for months on end.

And yet to the larger music industry, video game music still seems to be a mystery. While boutique labels like LA’s iam8bit and London-based Data Discs have found success in creating limited-edition vinyl pressings of retro and indie game soundtracks (many of them drop-dead gorgeous), and Ghostly released C418’s soundtrack for Minecraft on vinyl last year, most of the larger indie labels in the U.S. have yet to jump on the game soundtrack bandwagon.
