Question: What kind of songs were included on the first release by the American heavy metal band consisting of  singer Russell Allen (Symphony X), guitarist Mike Orlando and drummer Mike Portnoy (ex-Dream Theater)?
Context: The Majesty Demos are the first recorded attempts of progressive band Dream Theater, under their original name, Majesty.  The original 1986 tape contained six tracks which were recorded on Mike Portnoy's analog 4-track recorder, and another 4-track recorder obtained from friends at Berklee College of Music.  All the band members were about 19 years old at the time of the recording.  Only 1,000 copies were recorded on cassette tape and distributed to fans and rock and metal magazines.  Portnoy gave one copy to Jim Matheos of Fates Warning, a move that was instrumental in the band's break into the progressive rock scene.  The line-up on the initial recording was keyboardist Kevin Moore, bassist John Myung, guitarist John Petrucci, and drummer Mike Portnoy.  Chris Collins, the band's singer at the time, had been introduced to the band after a friend heard a demo of him singing a note-for-note version of Queensrÿche's "Queen of the Reich".

Atomic Soul is Symphony X's lead singer Russell Allen's debut solo album.  It was released on April 26, 2005.

The album was released in 2005 on the InsideOut Music label.  Allen played bass and keyboards on most tracks, along with vocals, but some of the tracks feature guests Robert Nelson on drums, Brendan Anthony and Jason Freudberg on guitars, Larry Salvatore on bass and Jens Johansson on keyboards.  Also Allen's bandmates Michael Romeo and Michael Pinnella, from Symphony X, are featured on the album. Thought Chamber is an American progressive metal supergroup formed in 2006.
