Critical response

Upon its release, the album received positive reviews from most music critics, based on an aggregate score of 80/100 from Metacritic.^[20] Allmusic writer Gregory Heaney commended Kweli's and Hi-Tek's musical chemistry and wrote "Hi-Tek's soul-infused beats create the perfect laid-back atmosphere for Kweli's casual verbal acrobatics, crafting beats that bring the listener into the group's chilled-out space with their minimal aesthetic".^[5] Steve Juon of RapReviews gave it a 9/10 rating and praised Kweli's rapping, stating "Kweli is using his keen powers of observation to see the world for what it really is, and then translate that knowledge into a musical form you can simultaneously enjoy and learn from".^[11] Exclaim!'s Anupa Mistry wrote that Revolutions per Minute is "doused in their working chemistry".^[21] Boston Phoenix writer Chris Faraone gave it 3 out of 4 stars and stated "The chemistry between these two remains bubbling".^[8] HipHopDX writer Kathy Iandoli gave it 4 out of 5 stars and wrote that it "displays the evolution of both the emcee and the deejay".^[22] Giving it an 8/10 rating, PopMatters writer Dave Heaton praised Kweli's lyrics concerning the importance of money in life, building a career in hip hop, the differences between celebrity and work, and the former's effect on a person, stating:

Taken as a whole, Revolutions Per Minute offers a specific and complicated vision of what it means to be an artist. It presents the notion that music-making is about dedication and practice, about practical business decisions as much as art, while also being a manner of “exorcising” ghosts and “testifying” to what’s going on in the world (as he puts it on “Back Again”). To sign a record deal is to enter a deal with the devil, and every musician needs to know it, Kweli notes repeatedly.^[10]

Giving it 4 out of 5 stars, Slant Magazine writer M.T. Richards described the album as "brainy, energizing stuff" and praised Kweli's rapping, stating "Sinking his no-frills flow into calm, bassy tracks, Kweli lands punchline after punchline with the kind of finesse Jay and Common could only dream of".^[12] The A.V. Club's Nathan Rabin gave the album a B rating and wrote "Hi-Tek lacks a trademark style, but his chemistry with Kweli remains potent, even when Minute doesn't hit the heights of the duo's debut".^[7] Mosi Reeves of Spin gave the album 3½ out of 5 stars and viewed Hi-Tek's "jazz-inflected riffs and soulful vibes" as complementary to Kweli's "mercurial" style, stating "congenial beats balance intricately daring rhymes".^[13] Alternative Press writer Casey Boland gave it four out of five stars and viewed it as an improvement for Hi-Tek's producing and Kweli's rapping, stating "he sounds at home with Hi-Tek. His cadence has never locked so tightly with the tune, his lyrical flow never so sinuous".^[6] Henry Adaso of About.com noted a "musical maturation" by the duo and wrote that the album "finds Kweli masterfully marrying the physical with the philosophical atop Hi-Tek's rich palette of headphone music".^[23] Pitchfork Media's Nate Patrin gave Revolutions per Minute a 7.5/10 rating and commended its "conscious yet unpretentious lyricism delivered with acrobatic dexterity over on-point, no-gimmick beats".^[9]
