The resurgence of cassettes may seem like a de-evolution of music listening to some consumers. If you agree, let First Base Tapes change your mind. The Boulder-based label cranks out limited runs of albums on tape, which go for $5 and are available for purchase through the First Base Bandcamp page. Acts like American Grandma, Male Blonding and Beat Soft Pop have put out colorful cartridges, which can also be streamed or downloaded, through the imprint. Many of its releases are recorded at independent, nonprofit station Radio 1190, located on the University of Colorado Boulder campus, where First Base Tapes was born. The label is a network of bands, sound engineers, visual artists and music fans who believe that DIY really means Do It Affordably and Do It Together.
