Knock Madness

Knock Madness was supported by three singles, "Old Friend", "Hop Is Back", and "Rip Your Heart Out", the last of which features Tech N9ne.

[3] On January 17, 2012, fellow Funk Volume rappers SwizZz and Dizzy Wright were confirmed to make appearances on the album.

[6] In September 2012, Hopsin confirmed that he would self-produce the majority of the album, with drummer Travis Barker producing one or two tracks.

[3] He also indicated the album would be released with a bonus CD that will have all the 'Ill Mind of Hopsin' songs remastered, however this ultimately did not take place.

[12]In the lead single "Hop Is Back", Hopsin pokes fun at Kendrick Lamar and disses Kanye West's newer music.

[13] Hopsin clarified his statements in an interview with HipHopDX saying he had no ill feelings towards Kendrick Lamar, and that he dissed West because he disliked his new music.

[15] For "Rip Your Heart Out" featuring Tech N9ne, Hopsin created what he called a "weird, funky, dope beat that you can just bop your head to.

Hopsin has said the meaning of the song was "to show what early wrong decisions can do to youngsters in the long run", as well as "what they can possibly miss out on.

[22] In December 2012, Hopsin hinted on his Facebook and Twitter pages that he and Travis Barker were working on a project together, though further details were withheld at the time.

[28] Hopsin, with the rest of the Funk Volume artists, went on a two-month worldwide tour in late 2012, which included 58 shows in 60 days throughout the United States, Europe and Australia.

They toured the West Coast of the United States and Hopsin performed material from the album for the first time.

[33] Dizzy Wright and DJ Hoppa joined Hopsin on select dates during the North American run of the tour.

[34] In an interview with ThisIs50, Hopsin released information on the album, stating that the first single would be named "Hop Madness".

[35] Hopsin confirmed via his Facebook and Twitter on January 5, 2012, that he would be shooting the "Hop Madness" video that month.

On July 17, 2013, Hopsin released the music video for "Old Friend" on both his YouTube channel,[39] and the single to iTunes.

[40] He later confirmed that the song is not the sixth in the "Ill Mind of Hopsin" series but rather the first single from Knock Madness.

[41] On August 18, 2013, Hopsin confirmed in a Facebook status that the lead single from Knock Madness, titled "Hop Is Back", would be released in a couple of weeks.

[50] Omar Burgess of HipHopDX classified the album as "Pop-tinged Horrorcore of the highest order", praising its "catchy hooks, accessible production and subject matter" as well as "Hopsin's raw technical ability" with regards to lyricism and wordplay.

In the end Burgess said, "When he [Hopsin] strikes the perfect balance between shock value, raw emotion and his immense skill set, that moment may yield a classic album.

stated that the album excels when Hopsin "focuses on external obsessions: ode to amateur skating 'Nollie Tre Flip' has the most enticingly offbeat rapping on the album, as well as a dizzying internal rhyme scheme, while 'Turn on the Lights' analogue 'Dream Forever' is heartfelt and raw.

"[53] David Jeffries of AllMusic praised the album's consistency for providing "shocking lyrics and infectious hooks", highlighting 'Rip Your Heart Out' featuring Tech N9ne as a standout track.

"[52] After only being released for three days, Knock Madness debuted at number 132 on the US Billboard 200, selling 4,000 copies in the United States.

Though the album's release date was originally scheduled for November 26, 2013, Funk Volume announced on their Facebook page on November 18 that it would be very hard to find Knock Madness in stores the first week of its release, due to a delay and few stores placing orders for the album.
