Air Museum blurs the lines between acoustic and electronic music even more without sacrificing melody or the delicacy of their sound. It is an album of firsts. It was the first album that the acoustic instruments were not processed via a computer. Instead, the processing of the instrumentation (acoustic and electric guitar, cello, accordion, piano, bass etc.) was done using a variety of pedals, modular synths, and other analog techniques. While acoustic instruments were used extensively, the album manifests itself sonically as their most 'electronic' record yet. Air Museum is also their first record that was made in a studio. Working in the studio expanded their possibilities, giving more room for experimentation. While much of the album was recorded in real time with minor editing, the band took the opportunity to utilize the studio as an instrument of sorts, investing a great amount of time in customizing their approach to post-production.
