NAMM, the National Association of Music Merchants (NAMM), holds two trade shows each year with displays, booths, classes, demonstrations, etc. concerning musical gear of all kinds. That includes recording, live sound, music-making, and everything.
In January, 2013, it was held in Anaheim, California. Now, they just announced the summer Namm, which will be July 11-13 in Nashville, Tennessee.
NAMM is an awesome place to be if you want to see all the latest in gadgets, especially if you are a gear-head like me. Journalists and bloggers (also, like me) can post from the show floor to tell their readers about the latest and greatest. Unfortunately for me, a temporary medical condition will prevent me going this July. But if you're interested, check out the site here: http://www.namm.org/
