The Experience Music Project a Seattle interactive museum named after the Jimi Hendrix Experience set to open June 23 will include a Jimi Hendrix gallery, a "Sky Church" performance space, a sound lab, a multimedia ride, a digital archive of images and music and a restaurant. The museum, designed by renowned architect Frank O. Gehry, will be part of the Seattle Center, also the site of the Space Needle. The museum, which will include more than 80,000 artifacts from popular music history, also will feature interactive exhibits that allow attendees to try out different instruments. Partly the brainchild of Microsoft co-founder Paul G. Allen, an avid collector of Hendrix memorabilia, the museum is named for the legendary Seattle guitarist's early trio. Opening festivities will include performances by musicians spanning a wide range of popular genres.
