With access to thousands upon thousands of songs of every solidly-defined or unclassified musical archetype that exists on this great planet of ours, rock music has entered a new world of sonic exploration that was only experimented with in years past. The concept of “fusion” and the blending of genres has been a staple of pushing the envelope in music, but for many years it was still almost taboo to mix certain instruments, compositional methods, or even the fans that followed these musical movements. Today, with ancient horn sections bellowing their way into foggy punk rock and string sections going toe-to-toe with electronica, it isn’t hard to understand why the Brooklyn chiptune-punk quartet Anamanaguchi is successful enough to come to the Bay Area twice in one year and sell out two of the most popular clubs in the SoMa district of San Francisco.
