Pump's big breakthrough arrived in 2017 with the explosion of his single "Gucci Gang," which rose to the Top Three of the Hot 100 by the end of the year and was certified triple platinum. He issued his debut mixtape, Lil Pump, in October, featuring appearances by Smokepurpp, Gucci Mane , Lil Yachty, and more. The effort hit number three on the Billboard 200 and rose to number two on the R&B/hip-hop chart. Later that year, Pump scored another hit with the booming "Welcome to the Party," a collaboration with Diplo French Montana and Zhavia Ward that landed on the Deadpool 2 soundtrack. Things continued upward in a viral motion from there, as Pump spent much of 2018 contributing features to big rapper's songs, showing up on tracks by Lil Yachty, Lil Rich, and BlocBoy JB, and rounded out the year with "I Love It," a collaborative single with Kanye West accompanied by a viral, Spike Jonze-assisted video. In February 2019, Pump released his sophomore effort, Harverd Dropout. The Warner Bros release featured a who's-who of guests including Lil Wayne, YG, Offset, Quavo and many more.
