Rappers B.o.B. and Lil Dicky will be the main acts for Lafayette College’s spring concert on May 7, the Lafayette Activities Forum announced Wednesday.

Instrum, a New York based DJ, will be the opening act.

David Andrew Burd, a.k.a. Lil Dicky, is a Pennsylvania based rapper best known for his singles “Save Dat Money,” and “Professional Rapper.” He’s also know for the music video for his song “Ex-Boyfriend,” which went viral, garnering over one million views in 24 hours. He has released one album to date, 2015’s “Professional Rapper,” which reached #1 on the US rap charts.

In a February 2014 interview with Boston Magazine, Lil Dicky said, “I really wanted to embody the exact opposite of [mainstream rap], and I think people are appreciating it. There just hasn’t been a voice for that normal dude when it comes to rap.”

Bobby Ray Simmons, a.k.a. B.o.B, is a rapper and singer from Decatur, Georgia. He gained mainstream success with his first album, “B.o.B Presents: The Adventures of Bobby Ray,” which included three chart-topping singles. His first single from the album, “Nothin’ On You,” was certified triple platinum in the US, selling over three million copies. His second single, “Airplanes,” was certified quadruple platinum, and his third, “Magic,” was certified double platinum.

He has released four albums to date, “B.o.B Presents: The Adventures of Bobby Ray,” “Strange Clouds,” “Underground Luxury,” and “Psycadelik Thoughts.”

B.o.B garnered attention earlier this year after posting on Twitter about how he believes that the earth is flat, contrary to all scientific thinking and evidence. He sent out a series of tweets, citing evidence that caused him to doubt the rotundity of the planet, including, “No matter how high in elevation you are… the horizon is always eye level … sorry cadets… I didn’t wanna believe it either.”  

Celebrity astrophysicist Neil Degrasse Tyson took to Twitter to debate his claims, according to an article on National Public Radio’s website. In response, B.o.B released a song on the online audio distribution platform SoundCloud, entitled “Flatline,” about the earth being flat. Tyson’s nephew responded with a track he wrote called, “Flat to Fact.”
