Donald Stetson Mason (born December 20, 1944) was a second baseman in Major League Baseball. He played for the San Francisco Giants and San Diego Padres.

Peter Phillips (born June 21, 1970), better known by his stage name Pete Rock, is an American record producer, DJ and rapper. He rose to prominence in the early 1990s as one half of the critically acclaimed group Pete Rock & CL Smooth. After the duo went their separate ways, Rock continued with a solo career that has garnered him worldwide respect, though little in the way of mainstream success. Along with groups such as Stetsasonic, A Tribe Called Quest, The Roots and Gang Starr, Rock played a major role in the merging of elements from jazz into hip hop music (also known as jazz rap). He is widely recognized as one of the greatest hip hop producers of all time, and is often mentioned alongside DJ Premier, the RZA, and J Dilla as one of the mainstays of 1990s East Coast hip hop production. Pete Rock is also the older brother and younger cousin, respectively, of rappers Grap Luva and the late Heavy D.

Pete Rock was born in The Bronx, New York, the sixth of seven children of Jamaican immigrant parents. His family moved to Mount Vernon, New York when he was seven years old. During high school, he met his future recording partner CL Smooth. According to Rock, his father was also a part-time DJ who had an impressive record collection. Rock would often accompany his father to a cricket club called Wembley in The Bronx and watch as he spun records for the guests. His first job was as a paperboy, in his neighborhood.

Andre Johnson (born 1970), better known by his stage name Jah Mason, also known as Iron Mason and Fire Mason, is a reggae singer/deejay from Jamaica, active as a recording artist since 1991.

Jah Mason was born in Jamaica's Manchester Parish, and grew up in a Christian family. During his childhood, he was nicknamed Perry Mason for his ability to resolve disputes, and it was under this name that his debut single "Selassie I Call We" was released in 1991 on Junior Reid's JR record label. In 1995 he joined the Bobo Ashanti order of the Rastafari movement, and began performing and recording as Jah Mason after linking up with the David House group. He had hits in Jamaica with "My Princess Gone" and "Lion Look", and also made guest appearances on singles by his friend Jah Cure. His first albums came in 2002 with Keep Your Joy and Working So Hard. Since then he has released albums at a rate of more than one a year, including Wheat and Tears and Princess Gone...The Saga Bed, both released in 2006 on Greensleeves Records and VP Records respectively, and the latter distributed by Warners. The Jamaica Gleaner, reviewing Wheat and Tears, commented on a lack of originality in Jah Mason's work but went on to say "clichés notwithstanding, the album is musical, and for hardcore reggae fans, the disc should provide enough of a vibe to chill with." David Jeffries of Allmusic described him as "an effortlessly agile artist able to communicate love, pathos, revolution, spirituality, and even sensuality on equal terms."

David Thomas "Dave" Mason (born 10 May 1946) is an English singer-songwriter, and guitarist from Worcester, who first found fame with the rock band Traffic. In his long career, Mason has played and recorded with many of the era's most notable rock musicians, including Jimi Hendrix, Delaney Bramlett, Michael Jackson, The Rolling Stones, Eric Clapton, George Harrison, Fleetwood Mac and Cass Elliot. Mason's best known song is "Feelin' Alright", recorded by Traffic in 1968 and later by many other performers, including Joe Cocker, who had a major hit with the song in 1969. For Traffic, he also wrote "Hole in My Shoe", a psychedelic pop song that became a hit in its own right. "We Just Disagree", Mason's 1977 solo hit written by Jim Krueger, has become a staple of Classic Hits and Adult Contemporary radio playlists.

Mason's tenure with Traffic was disjointed. He co-founded the group, but left following the recording of their debut album, Mr. Fantasy (1967), only to rejoin halfway through the sessions for their next album, Traffic (1968), after which he left again. Last Exit (1969), a compilation of odds and ends, features little material by Mason apart from his song "Just For You". Traffic later re-formed without Mason, although he briefly toured with the band in 1971 as captured on Welcome to the Canteen. Even during his brief spells with the group, Mason never quite fit in; Steve Winwood later recalled "We all [Winwood, Jim Capaldi, and Chris Wood] tended to write together, but Dave would come in with a complete song that he was going to sing and tell us all what he expected us to play. No discussion, like we were his backing group."

Barbara Mason (born 9 August 1947, Philadelphia, Pennsylvania) is an American R&B/soul singer best known for her 1965 hit song, "Yes, I'm Ready".

A soul singer, Mason initially focused on songwriting when she entered the music industry in her teens. As a performer, though, she had a hit single in 1965 with her self-penned Top 10 hit, "Yes, I'm Ready" (number five pop, number two R&B), a fetching soul-pop confection that spotlighted her high, girlish vocals. One of the first examples of the sweet, lush sound that came to be called Philly soul, she had modest success throughout the rest of the decade on the small Arctic label, reaching the Billboard Hot 100 Top 40 again in 1965 with "Sad, Sad Girl", and "Oh How It Hurts" in 1967-68.

In the early and mid 1970s, Mason toughened her persona considerably, singing about sexual love and infidelity with a frankness that was uncommon for a female soul singer in songs like "Bed and Board," "From His Woman to You," and "Shackin' Up." Sweet soul continued to be her groove, and she continued to write some of her material. But the production, as it was throughout soul in the '70s, was more funk-oriented, and at times Mason would interrupt her singing to deliver some straight-talkin' raps about romance. Curtis Mayfield produced her on a cover version of Mayfield's "Give Me Your Love," which restored her to the pop Top 40 and R&B Top Ten in 1973; "From His Woman to You" (the response to Shirley Brown's single "Woman to Woman") and "Shackin' Up" were also solid soul sellers in the mid '70s. After leaving Buddah Records in 1975, she only dented the charts periodically, with "I Am Your Woman, She Is Your Wife" (1978), "Another Man" (1984) on West End Records, and a couple of other singles.
