James Dewees is Reggie and the Full Effect. That much we now know. For a long time the question hovered around the music industry, Who is Reggie and where did he come from the confusion was understandable since Reggie albums were filled with skits, guest character appearances, and the ramblings of crazy crack heads. Reggie's last studio album, 'Under the Tray', threw everyone for a loop with the emergence of a character named Paco, an ex-con turned rock star. Truth is James Dewees is not only Reggie, but also keyboardist for seminal rock band the Get Up Kids. So we also know James can bring a serious side. Fontana. 2005.
