Marcus Jamal Hopson (born July 18, 1985), known professionally as Hopsin, is an American rapper, songwriter, and record producer from Los Angeles, California.

His successor label, Undercover Prodigy was launched in a joint venture with 300 Entertainment in 2016, through which he released his fifth album, No Shame (2017) to lesser commercial success and mixed critical reception.

In addition to his own output, Funk Volume has signed and released projects for aesthetically-similar regional artists SwizZz and Dizzy Wright, as well as Southern rapper Jarren Benton before its dissolution in 2016.

[8] Upon his release, he began to pursue a career in music, purchased a microphone, and installed FL Studio (known as FruityLoops at the time) on his computer.

[11] He was originally hailed as one of the driving forces behind attempting to bring Ruthless Records back to previous glory.

[15] Shortly before the departure from Ruthless Records, Hopsin founded his own independent label, Funk Volume, with Damien Ritter.

SwizZz, Damien Ritter's younger brother and a former classmate of Hopsin at Monroe High, was the first artist to be signed to Funk Volume.

Shortly after launching Funk Volume, both Hopsin and SwizZz released a collaborative mixtape titled Haywire in June 2009 to promote the label.

[16] Funk Volume originally wanted to sell it for retail sale, but were unable due to Hopsin still being contracted by Ruthless Records at the time.

[18] On October 8, 2010, Hopsin released a music video for the song "Sag My Pants", the second single off Raw on YouTube.

[19] In the song Hopsin pokes fun and disses other rappers such as Lil Wayne, Drake, Soulja Boy, Lupe Fiasco, Rick Ross and Tomica Wright, the owner of Ruthless Records.

In January 2012, Hopsin landed a spot on MTV2's "Sucker Free Sunday" by appearing in Tech N9ne's music video for "Am I A Psycho?".

[22] In February 2012 Hopsin appeared on the front cover of XXL as part of their annual "Top 10 Freshmen list" along with fellow rappers French Montana, MGK, Danny Brown, Roscoe Dash, Iggy Azalea, Macklemore, Don Trip, and Kid Ink.

"[31] Hopsin and the rest of the Funk Volume artists went on a three-month worldwide tour in the fall of 2012 which included 58 shows in 60 days in the United States, Europe, and Australia.

[39] Knock Madness was released on November 26, 2013, by Funk Volume and debuted at number 76 on the Billboard 200 with first-week sales of 12,000 copies.

The album contains guest appearances from SwizZz, Dizzy Wright, Jarren Benton and Tech N9ne along with being production primarily by Hopsin himself.

Following the Knock Madness tour beginning in December 2013, Hopsin planned to go on a hiatus also saying, "When I take a break, I am still going to be making music, I am [just] not going to be out publicly promoting shit.

However, on December 25, 2014, Hopsin shared a video on his YouTube channel called "The REAL reason Hopsin left the music industry" with label mate Jarren Benton inspired by the film Dumb and Dumber To which stated that he was not quitting rap and it was all a joke, also revealing that he will be releasing a new album called Pound Syndrome in 2015.

[54] Hopsin officially left Funk Volume after the song's release and went on to create a new label called Undercover Prodigy.

[85] In September 2020, Hopsin joined the advisory board of music social networking startup Artist Republik.

[21] Hopsin said that he hates Odd Future's music, noting its negativity and "random" lyrical content and criticizing the group's production values.

[93] Hopsin was detained shortly thereafter once police responded to the initial call stemming from the altercation inside the club.

[97][98] The video was also initially taken down by YouTube for including nudity; Hopsin criticized the decision, stating that there were no visible nipples and he wore a “dick sock” to hide his genitalia.

[101] Hopsin got his start in entertainment appearing as a background extra in movies and Disney Channel TV shows such as John Tucker Must Die, Even Stevens, Lizzie McGuire, Cold Case, Malcolm in the Middle and Gilmore Girls among many others.

[104] In 2004, Hopsin began wearing colored eye contacts in appearances in interviews, music videos, and performances.

In some of his tracks, such as "Nocturnal Rainbows", he emphasizes his dislike for drugs (most notably crystal meth) and the irreversible damage they are capable of.

Hopsin has stated that he tries to be a hip hop musician who can instill positive influences in people who listen to his music.
