The Nu Shooz, the band know for the song "I Can't Wait," are part of a group of Portlanders who've traveled to Japan to volunteer in the disaster zone. They're bringing their gift of music to the group and the victims. Lead singer Valerie Day says it's been a unique experience so far.  They'll join a smaller group next at a shelter in Sendai and perform for the victims whenever it feels right.  When Portland-based Nu Shooz were asked to be musical ambassadors on the Flight of Friendship goodwill mission to the disaster areas in Japan, they said "yes" and they're impressed by the diverse group that's joined the effort. John Smith adds that they're not sure if they'll perform for tsunami survivors, but they're fine with just helping to pass out supplies. They'll work in a shelter in Sendai, Japan for the next couple of days.
