As glorious as it is to attend a NAMM show and see acres of pristine, in-the-box musical gear, it's hard to escape the feeling that retailers are trying to reinvent the wheel and find new ways to separate you from your money. Maybe that tweak Evans made to its drum head design is revolutionary, or maybe that's just this year's fancy sales pitch. In any event, I took to the NAMM showroom floor on Sunday to seek out some of the more unusual offerings in the convention. Whether they're the new concepts that will help you reinvent your sound, we'll leave to you to decide.
