I found Marco Lucchi via the Microsound and Ambient mailing lists. His site features a lot of music, with some interesting live ambient pieces. From what I’ve listened to so far his music feels quite gentle and thoughtful, everything I’ve downloaded is excellently produced. He seems to be able to mix melodic ambient music with more experimental sounds very effectively. The live ‘Tantra’ pieces are definitely pleasant on the way home after a hectic day in the office!
