"Grindin'" is the first single from the Virginia Beach rap duo Clipse. The song was produced by The Neptunes, and featured on the Clipse's debut album, Lord Willin'. The song became a summer Top 40 hit, reaching #30 on the Billboard Hot 100 on July 30, 2002.
Arguably the most iconic track of The Neptunes' early-decade influence on hip-hop production, the beat was far more sparse in its percussive drum and woodblock arrangement than most popular hip-hop tracks at the time, predating later sparse Neptunes productions like Snoop Dogg's " Drop It Like It's Hot" that would further capitalize and expand on this style. It bares notable and acknowledged similarity to 1980s hip hop tracks such as Eric B & Rakim's "My Melody".
There were two official remixes released: one featuring new verses by Pusha T and Malice featuring Noreaga, Birdman and Lil Wayne, and the other, a selector remix featuring dancehall artists Sean Paul, Bless and Kardinal Offishall. Both remixes feature the same instrumental but a different verse performed by Pusha T.
Pusha T stated that Pharrell nearly gave the beat to Jay-Z.
The song is featured in the popular video games Saints Row and NBA 2K15. The intro was also used in the 2003 comedy film Malibu's Most Wanted.
