Problem: Background: P.M. Dawn was an American hip hop act, formed in 1988 by the brothers Attrell Cordes (known by his stage name Prince Be, sometimes credited as Prince Be the Nocturnal) and Jarrett Cordes (known as DJ Minutemix) in Jersey City, New Jersey. They earned significant crossover success in the early 1990s with music that merged hip hop, older soul, and more pop-oriented urban R&B. After recording their debut single "Ode to a Forgetful Mind" in 1988, P.M. Dawn released their first album Of the Heart, of the Soul and of the Cross: The Utopian Experience in 1991 to critical acclaim.
Context: Of the Heart, of the Soul and of the Cross featured the international hit "Set Adrift on Memory Bliss", which sampled the Spandau Ballet song "True", and featured a cameo by Spandau Ballet singer Tony Hadley in the music video of the song. "Set Adrift on Memory Bliss" hit #1 the week of November 30, 1991, and holds the distinction of being the first #1 song on the Billboard Hot 100 chart following the introduction of Nielsen SoundScan to the chart. The song also reached #3 in the United Kingdom. "Paper Doll", which was one of the early singles Island released in the United Kingdom, was released in the US as a follow-up to "Set Adrift on Memory Bliss", and peaked at #28 in early 1992. "Paper Doll" is said well over 100 times in the song, which makes it second only to MC Hammer's "Pray", which holds the record for the most times a title is repeated in a US Top 40 hit (147). With the success of their debut album, the band parted company with their manager Nick Hemmings and embarked on a world tour. During this world tour, Prince Be gave an interview to Details magazine in which he expressed skepticism of rapper KRS-One's activism: "KRS-One wants to be a teacher, but a teacher of what?" KRS-One and his crew, Boogie Down Productions, responded by storming a P.M. Dawn concert, forcing the group off the stage and performing their songs "I'm Still #1" and "The Bridge Is Over". Defending his actions to USA Today's James T. Jones IV, KRS-One remarked, "I answered his question. 'A teacher of what?' I'm a teacher of respect." In 1992, P.M. Dawn appeared on the Red Hot Organization's compilation CD Red Hot + Dance, contributing the Richie Rich Mix of "Set Adrift on Memory Bliss". The album, featuring George Michael and Madonna among others, was meant to raise money and awareness in support of the AIDS epidemic.

Background: Lehrer was born in 1928 to a Jewish family and grew up in Manhattan's Upper East Side. Although he was raised Jewish, Lehrer became an agnostic. He began studying classical piano at the age of seven, but was more interested in the popular music of the age. Eventually, his mother also sent him to a popular-music piano teacher.
Context: In 1953, inspired by the success of his performances, Lehrer paid $15 for some studio time to record Songs by Tom Lehrer. The initial pressing was 400 copies. At the time, radio stations would not give Lehrer air time because of his controversial subjects. He sold his album on campus at Harvard for $3 (equivalent to $27.00 today), while "several stores near the Harvard campus sold it for $3.50, taking only a minimal markup as a kind of community service. Newsstands on campus sold it for the same price." After one summer, he started to receive mail orders from all parts of the country (as far away as San Francisco, after The Chronicle wrote an article on the record). Interest in his recordings was spread by word of mouth; friends and supporters brought their records home and played them for their friends, who then also wanted a copy. Lehrer later recalled, "Lacking exposure in the media, my songs spread slowly. Like herpes, rather than ebola." The album--which included the macabre "I Hold Your Hand in Mine", the mildly risque "Be Prepared", and "Lobachevsky" (regarding plagiarizing mathematicians)--became a cult success via word of mouth, despite being self-published and without promotion. Lehrer embarked on a series of concert tours and in 1959 recorded a second album, which was released in two versions: the songs were the same, but More of Tom Lehrer was studio-recorded while An Evening Wasted with Tom Lehrer was recorded live in concert. In 2013, Lehrer recalled the studio session for "Poisoning Pigeons in the Park," which referred to the practice of controlling pigeons in Boston with strychnine-treated corn: "The copyist arrived at the last minute with the parts and passed them out to the band... And there was no title on it, and there was no lyrics. And so they ran through it, 'what a pleasant little waltz'... And the engineer said, '"Poisoning Pigeons in the Park,' take one," and the piano player said, '"What?"' and literally fell off the stool."
