Alan Ranta of PopMatters gave the album 8 stars out of 10, saying: "It is too intelligent and challenging to the status quo for the mainstream media to truly embrace, and Anti- seems to be lacking a little on the side of their hip-hop promotion department."[9] Mosi Reeves of Spin gave the album 3.5 stars out of 5, writing: "Extraordinarily irrational and willfully convoluted, Jhelli Beam is avant-rap as quantum physics."[10]
The opening track, "Split Seconds (Between Nannies and Swamis)", was described by Thomas Quinlan of URB as "Busdriver's simplest, most accessible rap jam, eschewing the bursts of rapid rap flows that usually accompany his slower style, and only occasionally bringing in a bit of sing-song."[11] He gave the album 4 stars out of 5, stating: "While there's some experimentation with new ideas here, Jhelli Beam is familiar enough to leave Busdriver fans more than satisfied."[11]
