Went to a conference last week for churches trying to break out of the "church box" and experienced some incredible worship take place.
Be sure to check out April Stace for some amazing harp/bass/d'jembre music. I bought the CD, and listened to it on the way home from San Diego. It's amazing how listening to harp music while driving in traffic on the 5 will turn normal merging traffic into an auto-ballet.
Also check out Tribela. It is a church in LA that makes extensive use of tribal drums (mostly d'jembres) to worship God. It was like walking through Libby park and seeing 30 people playing drums, only they were playing them for God as worship.
