Bryson Tiller shows off his definition of 'Trapsoul' at sold-out First Ave

Don't overlook Bryson Tiller. The 23-year-old from Louisville sold out his first show at First Avenue Sunday with lines wrapping around the building before show time.

While he isn't a household name yet, Tiller's music is already a favorite among chart toppers and radio heavyweights, such as Drake and the Weeknd. Like them, Tiller is blurring the lines between rapping and singing. His debut album "Trapsoul," stylistically represents its namesake. Dubbed the first post-Drake album by the New York Times, it's racking up millions of listens online with its blend of honest lyrics and brooding, slowed-down beats. Unlike Drake, Tiller has soulful vocal chops, which he shows off like a rugged Omarion, an artist he idolized growing up.

Tiller's 2014 hit, "Don't," peaked at No. 13 on the pop charts. On the track, he's the guy who says he can treat you better than your current beau.

"I guess he didn't know any better," Tiller rap-sings to his lady. "Girl, that man didn't show any effort."

But then in "Sorry not Sorry," Tiller flips the switch to a rap – sounding like a rage text you sent to an ex after you've broken up.

"I know you thought we had something special," he raps. "But you don't mean nothing to me."

His songs flirt between sultry R&B love songs about souring relationships to putting in the effort to make a relationship work.

Tiller brought out the trap with his song "Rambo." Tiller shoots verbal blows out to his competition with lyrics like: "This ain't temporary, I've been out here letting them know." Tiller received a shout out from the original Rambo, Sylvester Stallone, on Twitter for his song.

Not long before Tiller was touring and taking Instagram pictures with celebs, he was working at Papa Johns and UPS to support his daughter. One day, Tiller got a call from Timbaland who told him to quit his job and kick start his music career.

He raps about his come up on the song, "Ten Nine Fourteen" (named for the date he dropped "Don't"). On it, he talks about breaking out of Derby city and garnering recognition from Drake.

At First Ave, the audience rapped and sang along with every lyric.

In between songs, Tiller shared snippets of himself with the crowd, who was Snachatting his every movement. Before "Sorry not Sorry," Tiller told the audience how he wrote the song after all his exes started reaching out to him once he found success.

Tiller wrapped up the packed show with his hit "Don't." He introduced the song with something his friend said that stuck with him:

"It's only going to take one song to change your entire life."
