There are three bands called As One.
1) As One is a Korean female duo consisting of Yi Min Young and Crystal Chae (에즈원). They were discovered by one of the former members of critically acclaimed Korean R&B group SOLID who attended their church one day and heard them sing. Go here 애즈원 for the correct link to their page.
2) As One is one of the recording aliases of Kirk Degiorgio. Kirk Degiorgio produces mellow electronic music, incorporating soul into Detroit techno. http://www.kirkdegiorgio.com/
