One of the many perks of my job is how often I run into unique musicians and people while buying new gear. On a run to grab a four piece drum set last month I arrived on the scene and noticed some unusual instruments hanging out in a room at the seller's house. The instruments were a marimba and a cajón, and both looked like they were made from hardware materials without any of the gimmicky finishes and flourishes found on commercial versions you see in music stores.
