Anaheim is even happier this week as NAMM 2010 opened with appearances by the most infamous of Rock Band(it) mamas and flashes of Quincy. Cookie Monster, Jackson Browne, Dick Dale were there too.

NAMM, The International Music Products Association is one the largest 'music products' conventions on the planet and has expanded over the years to include facets of the industry from goods and retailers to publishers and performers.

If that sounds vague, massive, and intriguing, it's because it is. NAMM continues through Sunday, January 17. Check out the Day 1 photos.
