Why are indie bands releasing new music at a much faster rate?

Since the beginning of indie-rock scene in the 1980s, bands have usually been putting out albums every two years, but within the last year-and-a-half, artists on indie labels like Domino, Polyvinyl, Sup Pop, Barsuk, Saddle Creek, and Matador have been putting out music at a more frequent rate - every couple of months there's something - single, EP, song for compilation - coming out. “People used to tour to support music, and now people put music out to support tours” - as indie musician Sasami Ashworth told Billboard. Polyvinyl Label Director Seth Hubbard shares her sentiment - “The model of never going away does seem to be like the new normal... Now with Spotify being what it is, and social media being what it is, the reality for a lot of artists is that they need to tour more often to make a living".
