Robert Berry is an American guitarist, vocalist and producer, best known for his work with Hush, 3, Ambrosia, Alliance & Los Tres Gusanos.

Berry's name came into the spotlight in 1988, when he teamed with Keith Emerson and Carl Palmer (of Emerson, Lake & Palmer fame) and formed the band 3. Their only album, To the Power of Three, drew much criticism for its radio-friendly and polished 80's sound, considering the progressive pedigree of both Emerson and Palmer. 3 disbanded in 1989 after a small tour supporting To the Power of Three. The first single released from the album, Talkin' Bout, penned by Berry, reached #9 on the Billboard Mainstream Rock Tracks chart.

Since the dissolution of 3, Berry has participated in several projects, including Tales from Yesterday, a tribute album to Yes. He was also involved in an abortive follow-up to GTR in which he replaced Steve Hackett. Material from this project and an unreleased second 3 album appeared on Berry's solo album Pilgrimage to a Point. Berry's current band Alliance is composed of Gary Pihl from the band Boston on guitar, David Lauser from the Sammy Hagar Band on drums and Alan Fitzgerald from Night Ranger on keyboards. Berry also has contributed songs to a number of film soundtracks, including the Anthony Michael Hall film Out of Bounds. In 1999, Berry produced and performed on The Wheel of Time, an album billed as a soundtrack to the Robert Jordan fantasy series The Wheel of Time.

Kenneth Wayne Shamrock (born Kenneth Wayne Kilpatrick; February 11, 1964) is an American mixed martial artist, UFC Hall of Famer and professional wrestler. Shamrock emerged as one of the biggest stars in the history of mixed martial arts, headlining over 15 main events and co-main events in the Ultimate Fighting Championship and Pride Fighting Championships during the course of his career and set numerous pay per view records with his drawing power. Shamrock is widely considered to be a legendary figure and icon in the sport of mixed martial arts. Shamrock was named The World's Most Dangerous Man by ABC News in a special entitled "The World's Most Dangerous Things" in the early part of his UFC career, a moniker which has become synonymous as his nickname.

Shamrock became known early on in the UFC for his rivalry with Royce Gracie. After fighting to a draw with Gracie in the inaugural Superfight, he became the first UFC Superfight Champion after defeating Dan Severn at UFC 6; the title was eventually renamed the UFC Heavyweight Championship when weight categories were introduced to the UFC. He was also the first foreign MMA Champion in Japan, winning the title of King of Pancrase. During his reign as the UFC Superfight Champion, he was widely considered the #1 mixed martial artist in the world. Shamrock was also ranked by Inside MMA as one of the top 10 greatest mixed martial arts fighters of all time.

Keith Noel Emerson (born 2 November 1944, Todmorden, West Yorkshire) is an English keyboard player and composer. Formerly a member of the Keith Emerson Trio, John Brown's Bodies, The T-Bones, The V.I.P.'s, P.P. Arnold's backing band, and The Nice (which evolved from P.P. Arnold's band), he was a founder of Emerson, Lake & Palmer (ELP), one of the early supergroups, in 1970. Following the breakup of ELP, circa 1979, Emerson had modest success with Emerson, Lake & Powell in the 1980s as well as with 3, with the album To the Power of Three. ELP reunited during the early 1990s, releasing the album Black Moon. Emerson also reunited The Nice in 2002 for a tour. His latest album, Keith Emerson Band featuring Marc Bonilla, was released in 2008.

Along with contemporaries Richard Wright of Pink Floyd, Tony Banks of Genesis, and Rick Wakeman of Yes, Emerson is widely regarded as one of the top keyboard players of the progressive rock era. Allmusic refers to Emerson as "perhaps the greatest, most technically accomplished keyboardist in rock history".

Carl Frederick Kendall Palmer (born 20 March 1950, Handsworth, Birmingham, England) is an English drummer and percussionist. He is credited as one of the most respected rock drummers to emerge from the 1960s. In addition, Palmer is a veteran of a number of famous English bands, including The Crazy World of Arthur Brown, Atomic Rooster, Emerson, Lake & Palmer, and Asia. Every original song Palmer has played on features a cow bell.

The Crazy World of Arthur Brown was founded by Arthur Brown, and their original drummer was Drachen Theaker. However, Theaker suffered from aviophobia, and this meant he could not tour with his bandmates when the time arose for them to tour overseas. Thus, Theaker was the drummer on the band's eponymous album, but afterwards, Palmer took his place, and became a permanent member of the band.^{[citation needed]}

After meeting up with a pair of other English musicians, Greg Lake, and Keith Emerson, the young musicians felt an "immediate chemistry", and by 1970, formed a band. In naming the new group, the trio chose their last names alphabetically as the band's name, Emerson, Lake & Palmer, also shortened to ELP. It was arguably the most successful band in his career. Palmer remained with ELP until they eventually disbanded in 1980. They developed a sound that merged art rock, jazz, electronica, pop rock and classical music and found fans within their peers and the public alike. During that time Palmer released only one single of his own developing a solo career that he managed alongside ELP, and other future bands, for the remainder of his career.^{[citation needed]} Emerson, Lake & Palmer subsequently reunited in the early 1990s and played the progressive rock circuit, especially in outdoor summer concerts, and released two new studio albums. In 1998, the members of ELP had a rather acrimonious falling-out and Lake left the band.

Simon Phillips (born 6 February 1957) is an English jazz, pop and rock drummer.

Phillips began to play professionally at the age of twelve in his father's (Sid Phillips) Dixieland band for four years. He was then offered the chance to play in the musical Jesus Christ Superstar. He quickly became a sought-after session player and in 1992, he released two instructional videos displaying some of his best work.

Phillips found an early prominence as the drummer on the 1976 LP 801 Live with Phil Manzanera and Brian Eno. He went on to play with a wide array of musicians including Big Jim Sullivan, Big Country, Toto, Steve Lukather and Los Lobotomys, Jeff Beck, Whitesnake, Jack Bruce, Brian Eno, Duncan Browne, Toyah, Mike Oldfield, Jon Anderson, Trevor Rabin, Gary Moore, 10cc, Mick Jagger, Ph.D., Joe Satriani, Russ Ballard, Mike Rutherford, Phil Manzanera, John Wetton, flamenco guitarist Juan Martin, Asia, Stanley Clarke, Jimmy Earl, Derek Sherinian, Nik Kershaw, Gordon Giltrap, Camel and Jordan Rudess.
