The Low End Theory

A month after the debut Phife Dawg learned he was diabetic and considered leaving. After talking with Q-Tip they agreed he would take a bigger part, and the album introduced the lyrical interplay between the two. The title referred to the status of black men in society and to bass frequencies. Most of it was recorded at Battery Studios in Manhattan from 1990 to 1991, on a Neve console that John Lennon had used. Q-Tip produced and Ali Shaheed Muhammad scratched and co-produced. Skeff Anselm produced two songs, Show Business and Everything Is Fair, programmed at Jazzy Jay's Studio in the Bronx. Pete Rock made the original beat for Jazz (We've Got), which Q-Tip recreated, and Q-Tip credits Rock in the outro.

The bassist Ron Carter played double bass on Verses from the Abstract, and agreed to take part on condition that the group avoid profanity. Mixing engineer Bob Power removed surface noise from the samples. Q-Tip layered drum sounds, using as many as three snare or bass drums to make one, and Buggin' Out was the first song on which he layered two breaks at once. Butter was meant to include a Q-Tip verse, but Phife Dawg insisted on rapping alone, so Q-Tip took only the chorus. Show Business started life as Georgie Porgie, and Jive rejected it as too homophobic before it was rewritten. During the sessions the group changed managers, from Kool DJ Red Alert to Chris Lighty at Rush Artist Management, and Jarobi White left to study the culinary arts, so his recorded verses were dropped.

Critics and Jive executives doubted its commercial prospects. It entered the Billboard 200 at number 45, which was also its peak, and went gold on 19 February 1992 and platinum on 1 February 1995. The Source gave it five mics, and NME's Iestyn George called it a quantum leap. AllMusic's John Bush wrote that it was the most consistent and flowing hip-hop album ever recorded. Rolling Stone ranked it number 154 in 2003 and number 43 in 2020, and in 2022 the Library of Congress added it to the National Recording Registry.
