I love Schiller - I have all of their (his - Schiller is really Christopher von Deylen - plus guests) albums, I think they are all great. The concert DVD's aren't too bad either. They've been compared to Enigma, but I don't think that's fair, though there are some occasional similarities, I think Schiller have a sound and style of their own. Obviously, if you like Enigma, you'll like Schiller, and if you like chillout/dance music, you will too, they have a soothing, gentle style, that is really different from the norm or the heavy trance/techno stuff that you hear.
