I think Wasamin will be in Guam (at the Hilton Resort Park) tomorrow for a concert to raise money for victims of earthquake and tsunami in Japan:

UPDATE: Saturday 19th March, 04:18 PM JST
TUMON BAY, Guam —
Members of AKB48, Japan’s top-selling all-girl pop group, will join with six local bands and an island cultural dance group to headline “Japan Aid,” an all-day concert on Sunday night the Hilton Guam Resort & Spa. Proceeds of the concert will benefit victims of the devastating earthquake and tsunami, which struck Japan on March 11.
The concert will be staged at Hilton Park, near the entrance of the 32-acre complex that is Hilton Guam Resort & Spa. Admission is a $15 donation, for the event that runs from 3 p.m. to 9 p.m. Food, drink, souvenirs, family activities and raffle tickets will be available at the venue. All proceeds will be donated to the Guam chapter of the American Red Cross, for transfer to the Japan relief effort.
AKB48 have been Japan’s top selling artists for five years, with 20 hit singles, several iconic music videos and a live stage show performed nightly in Tokyo’s Akihabara district. Two members of AKB48, Iwasa Misaki and Suzuki Mariya, will perform and sign autographs at the “Japan Aid” concert.
