Blink and you'll miss it. Glance and you'll think it's closed. Yet inside the low, brown, adobe complex beyond the sign declaring "DRUMBEAT" in all-black caps is a little look at the Valley's often-overlooked Native culture. A wooden door opens to a tight space packed with crafting materials ranging from bird feet behind glass and dyed canary-yellow feathers to a color wheel of tiny Japanese seed beads packed into tubes. Venture toward the back for selections of releases from Canyon Records, hard-to-find cassette tapes, and shelves of Pendleton serapes, pillows, and Chief Joseph blankets in a dizzying spectrum of teals, purples, and fuchsias.
