In the summer of 2005, a member of his church approached Morse to tell him that he should make an album based on the tabernacle and that he should keep it a secret. Morse nonetheless mentioned that he was working on a secret project before he had written a note or even committed himself to do the project. Mentioning it during a radio interview created enough buzz to convince him to make the album. There was a contest on his message board to guess the participants, theme, and meaning of the album based on a series of clues. The secret project was finally revealed to be "?" (also known as The Question Mark album, rumored to be influenced in title by The White Album) and is about the tabernacle in the wilderness and the tabernacle of the heart. The studio band is Neal, Mike Portnoy, and Randy George with guests Mark Leniger, Alan Morse, Roine Stolt, Steve Hackett, and Jordan Rudess.
