How did Kane Brown go from “working two jobs, trying to afford my truck and playing XBox,” as he describes in a new Amazon Music mini-doc, to a country music super star?

Quickly, and with lots of help from his social media followers and real-life friends, family and management.

In “Velocity,” a 16-minute documentary released Thursday, Brown travels not that far back in time to the beginning of his career, in what started as a ploy to get social media followers. Starting in 2014, Brown filmed himself singing covers of famous songs and posted them to Facebook.

He admits he wanted the clips to go viral, but never imagined they’d lead to a record deal or real fame.

But both those things came. Brown released his eponymous first studio album in 2016, which peaked at No. 5 on Billboard's albums chart. Two years later, his follow-up album "Experiment" took the No. 1 spot on Billboard. Brown has had eight No. 1 hits so far and earned numerous CMT and American Music Awards.

Reflecting on his rise to the top, Brown cringes at his fashion choices (on those sleeveless plaid shirts he used to wear: “I thought I looked good…it was awful though.”), rejoices at becoming a father (saying, “She’s my life,” of daughter Kingsley Rose) and reels from the sudden death of his drummer Kenny Dixon.

The doc takes fans inside the Staples Center, the iconic LA venue where Brown is only the 11th country act to headline, according to Amazon.

Preparing for his Jan. 9 concert, Brown shows fans that after a few years of opening for Florida Georgia Line, Jason Aldean and Brad Paisley, he’s ready to take on his own arena tour.

“It’s just fun now,” Brown said.

North American shows of Brown's "The Worldwide Beautiful Tour" kick off Feb. 29 in Atlantic City, New Jersey, and wrap Aug. 22 in Calgary, Alberta.
