Though recently released, this one is actually pretty old! I'll go ahead and quote their bandcamp page here.
Here is our Incredably difficult second release which has taken nine years to actually release. We got carried away with the recording by using way to many mics on the guitar amp and way too many takes multi tracking and adding extra instruments computers were a lot slower nine years ago and we ended up with an over welming 26 Gigabytes of sound files.
This was my first exposure to Mustard Allegro. Though the first track is pretty straight-ahead surf, the rest of it is very inventive, with nontraditional instrumentation, jazzy and noisy moments. Check it out!
