Herb Shuttles is the 6th track off of the Underachievers debut mixtape, Indogoism. With precise and rapid flow accompanied with an aggressive instrumental produced by Roca Beats, Herb Shuttles grew to be one of the most popular UA songs ever. In an interview with Complex, Issa Gold explained that this song was essentially what got them signed with their Flying Lotus/Brainfeeder record label. He said:

It was never blatant [with Flying Lotus] like, ‘Alright, [I’m signing you guys because of ‘Herb Shuttles.’]’ But that’s when it happened, coincidentally. It was like, ‘Bam,’ two days later, a day later. [He was probably] like ‘Alright, let me not procrastinate on this, because [people are going to come knocking on their door now.’]’
