David Leaf (born April 20, 1952) is an American writer, producer and director known for documentaries, music programs and pop culture retrospectives. Among his best known documentaries are The Night James Brown Saved Boston (2008), The U.S. vs. John Lennon (2006) and Beautiful Dreamer: Brian Wilson and the Story of SMiLE (2004). He also wrote the Brian Wilson biography The Beach Boys and The California Myth (1978).

David (Hebrew: דָּוִד, דָּוִיד, Modern David Tiberian Dāwîḏ; ISO 259-3 Dawid; Strong's Daveed; beloved; Arabic: داوود‎ or داود‎ Dāwūd) was, according to the Hebrew Bible, the second king of the United Kingdom of Israel and, according to the Gospel of Matthew and the Gospel of Luke, an ancestor of Jesus. David is seen as a major Prophet in Islamic traditions. His life is conventionally dated to c. 1040–970 BC, his reign over Judah c. 1010–1003 BC,^{[citation needed]} and his reign over the United Kingdom of Israel c. 1003–970 BC.^{[citation needed]} The Books of Samuel, 1 Kings, and 1 Chronicles are the only sources of information on David, although the Tel Dan stele records "House of David", which some take as confirmation of the existence in the mid-9th century BC of a Judean royal dynasty called the "House of David".

David is very important to Jewish, Christian and Islamic doctrine and culture. In Judaism, David, or David HaMelekh, is the King of Israel, and the Jewish people. Jewish tradition maintains that a direct descendant of David will be the Messiah. In Islam, he is known as Dawud, considered to be a prophet and the king of a nation. He is depicted as a righteous king, though not without faults, as well as an acclaimed warrior, musician, and poet, traditionally credited for composing many of the psalms contained in the Book of Psalms.

Brian Douglas Wilson (born June 20, 1942) is an American musician, best known as the leader and chief songwriter of the group The Beach Boys. On stage, Wilson provided many of the lead vocals, and often harmonized with the group in falsetto. Early during his on-stage career, Wilson primarily played bass on stage, but gradually transitioned to primarily playing piano/keyboards. Besides being the primary composer in The Beach Boys, he also functioned as the band's main producer and arranger. After signing with Capitol Records in mid-1962, Wilson wrote or co-wrote more than two dozen Top 40 hits including "Surfin' Safari", "Surfin' USA", "Shut Down", "Little Deuce Coupe", "Be True to Your School", "In My Room", "Fun, Fun, Fun", "I Get Around", "Dance Dance Dance", "Help Me Rhonda", "California Girls" and "Good Vibrations". These songs and their accompanying albums were internationally popular, making The Beach Boys one of the biggest acts of their time.

In the mid-60s Wilson used his increasingly creative ambitions to compose and produce Pet Sounds, considered one of the greatest albums of all time. At this point his music was considered to rival that of Lennon–McCartney. The intended follow up to Pet Sounds, Smile, was cancelled for various reasons, including Wilson's deteriorating mental health. Wilson's contributions to The Beach Boys diminished as the years went by, and his erratic behavior led to tensions with the band. After years of treatment and recuperation, he began a solo career in 1988 with Brian Wilson, the same year that he and The Beach Boys were inducted into the Rock and Roll Hall of Fame. Since then he has toured for the first time in decades with a new band and released acclaimed albums such as a reworked version of Smile in 2004, for which Wilson won a Grammy Award for "Mrs. O'Leary's Cow (Fire)" as Best Rock Instrumental, That Lucky Old Sun, and Brian Wilson Reimagines Gershwin.

James Joseph Brown (May 3, 1933 – December 25, 2006) was an American singer, songwriter, musician, and recording artist. He is the originator of funk music and is a major figure of 20th century popular music and dance.

In a career that spanned decades, Brown profoundly influenced the development of many different musical genres. Brown moved on a continuum of blues and gospel-based forms and styles to a profoundly "Africanized" approach to music making. Brown performed in concerts, first making his rounds across the Chitlin' Circuit, and then across the country and later around the world, along with appearing in shows on television and in movies. Although he contributed much to the music world through his hitmaking, Brown holds the record as the artist who charted the most singles on the Billboard Hot 100 without ever hitting number one on that chart.

For many years, Brown's touring show was one of the most extravagant productions in American popular music. At the time of Brown's death, his band included three guitarists, two bass guitar players, two drummers, three horns and a percussionist. The bands that he maintained during the late 1960s and 1970s were of comparable size, and the bands also included a three-piece amplified string section that played during ballads. Brown employed between 40 and 50 people for the James Brown Revue, and members of the revue traveled with him in a bus to cities and towns all over the country, performing upwards of 330 shows a year with almost all of the shows as one-nighters. In 1986, he was inducted into the Rock and Roll Hall of Fame and in 1990 into the Songwriters Hall of Fame.

David Lanz (born June 28, 1950 in Seattle, Washington) is a Grammy-nominated New Age pianist. His most popular album, Cristofori's Dream, topped the New Age charts in 1988, which was No. 1 on Billboard's first adult alternative/New Age chart for 27 weeks and eventually sold platinum. Natural States peaked at No. 125 on the Billboard 200.

Lanz attributes his interest in the piano to experiences during his childhood in the Pacific Northwest. He said, "As children, the piano is one of the first 'machines' we come in contact with, and one of the first we are allowed to explore."

One of the other reasons that he enjoyed the piano was his mother. His mother played songs by Ray Charles, Frank Sinatra, and Nat King Cole on the piano, and became David's first musical mentor.

Lanz started his performing career as a teenager during the 1960s. In 1971, Lanz recorded one album for Mercury Records with Canadian group- Brahman. He played keyboards on the Terry Jacks' hit, "Seasons in the Sun". In the late 1970s, Lanz was musical director of the Seattle band, The Sweep, with Ken McCann as front man singer, Peter Pendras on lead guitar, Glenn Ayers on drums, and Hugh Gerrard on bass. Saxophonist Robbie Jordan was added to the group after a gig in Boise, Idaho. A childhood friend of Lanz', Jeff Simmons, at one time or another played with or filled in for Sweep personnel since Simmons is a multi-instrumentalist.
