2003-07-15 James Iha completes the circle
With barely a week left until A Perfect Circle headed out on the road to tour, James Iha of the Smashing Pumkins came to LA to join the band. Though he knew all the songs from Mer de Noms, it was an intense week of practice to integrate within the dynamics of the band... and to learn a slew of new songs.

Reportedly James has a banshee yell that rivals his guitar playing in terms of raw volume and gut wrenching emotion.
