Pet Rocks were a 1970s fad conceived in Los Gatos, California by advertising executive Gary Dahl.

In April 1975, Dahl was in a bar (which is now Beauregard Vineyards Tasting room in Bonny Doon) listening to his friends complain about their pets. This gave him the idea for the perfect "pet": a rock. A rock would not need to be fed, walked, bathed, groomed and would not die, become sick, or be disobedient. He said they were to be the perfect pets, and joked about it with his friends. However, he eventually took the idea seriously, and drafted an "instruction manual" for a pet rock. It was full of puns, gags and plays on words that referred to the rock as an actual pet.

The first Pet Rocks were ordinary gray stones bought at a builder's supply store. They were marketed like live pets, in custom cardboard boxes, complete with straw and breathing holes for the "animal." The fad lasted about six months, ending after a short increase in sales during the Christmas season of December 1975. Although by February 1976 they were discounted due to lower sales, Dahl sold 1.5 million Pet Rocks and became a millionaire.

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.

CL Smooth (born Corey Brent Penn, Sr., October 8, 1968, New Rochelle, New York) is an American rapper, poet, and is best known as the vocal half of the hip-hop duo Pete Rock & CL Smooth.

After the pair split in 1995 Pete Rock, whose work with CL had garnered him a reputation as one of the most acclaimed producers in hip-hop, went on to produce (and remix) tracks for dozens of marquee-name and/or well-respected acts, and to release a batch of solo and instrumental albums. C.L. Smooth remained musically inactive.

The pair managed to reconcile their differences only long enough to record five isolated tracks in the ten years since their split: "Da Two," "Back On Da Block," "Fly 'Til I Die," "Appreciate," and "It's A Love Thing." There were talks of a definitive reunion and a new album in 2004; however, the speculation was dismissed by both parties after another fallout.

During his period of hiatus, C.L. Smooth declined even to appear as a guest on other artists' albums, with the exception of "Only the Strong Survive" with DJ Krush in 1996. Recently, however, he has contributed featured guest vocals to songs by AZ ("Magic Hour"), Nujabes ("Sky is Falling") and Dipset affiliate J. R. Writer (the remix of "Mesmerize") or Supafuh ("Act of Faith").
