Inventions was formed by longtime friends, tourmates, and labelmates Matthew Cooper of Eluvium, and Mark T. Smith of Explosions In The Sky. There are plenty of talking points here: The fact that Cooper hasn t been in a "band" of any sort since he was a teenager; no member of Explosions In The Sky has released an album outside of the context of EITS since their inception in the late 90s; and, of course, this is a dream duo for anyone familiar with the unparalleled emotional resonance of Cooper and Smith s respective day jobs.
