Sherinian, "Derek Sherinian will be at least one chapter in my book when I write my autobiography. He is the Caligula of the keyboards. He was born with the rock star charisma. Reeking of self-esteem, he walked into our first rehearsal for the 'Trash' tour and flawlessly auditioned by playing every classic Bob Ezrin keyboard part to the note. Ten years later and thousands of exchanged poker chips later, the two of us have probably broken even. He once pulled four twos on the bullet train from Japan, and won a huge poker pot. I'll always remember that day... him jumping up on the very conservative bullet train, screaming that he'd pulled four twos, which is an awfully good hand in poker. Dream Theater In 1994, Sherinian replaced Kevin Moore in the progressive metal/progressive rock band Dream Theater, originally just for the band's promotional tour for Awake. In February 1995, however, he was made a full-time member of the band. Dream Theater guitarist John Petrucci added "...Derek -considering the fact that he's heavily into guitarists and rock music, his history, and the range of all the great guitarists he's worked with —plays with a fire unheard of from most keyboardists." He recorded the albums A Change of Seasons (1995), Falling into Infinity (1997), and Once in a LIVEtime (1998) with Dream Theater before being replaced in January 1999 by Jordan Rudess due to creative differences and turmoil within the band. Sherinian reunited with Dream Theater for a one-off concert in 2004, which was recorded and released as When Dream and Day Reunite (2004). The band's performance of "Metropolis Pt. 1" featured an extended improvisation between Sherinian, Rudess, and guitarist John Petrucci. During the late 1990s, Sherinian released two albums with the progressive rock supergroup Platypus, which also featured Dream Theater bassist John Myung, Dixie Dregs drummer Rod Morgenstein, and King's X guitarist Ty Tabor. The group released two albums, When Pus Comes to Shove (1998) and Ice Cycles (2000), before disbanding in 2000. In 2002, he was part of the band Jughead, which also included Tabor, bassist/vocalist Matt Bissonette and drummer Gregg Bissonette. In January 2012, Sherinian performed at two shows with instrumental supergroup Mike Portnoy, Billy Sheehan, and Tony MacAlpine (PSMS) for the Guitar Center Drum Off, and Sabian Live. In the fall of that year, PSMS began rehearsing for a tour and a video of their rehearsal was
