Andy Mineo spent four days in the studio working on his new album in Los Angeles this week, according to his team’s social media accounts.

Reach Records producers Alex Medina, Gawvi and Joseph Prielozny appeared in several tweeted photographs. Medina and Prielozny played large roles on Mineo’s debut album Heroes for Sale — producing a total of six tracks — while Gawvi produced the third single of the project, “You Will.”

Wordsplayed and Natalie Lauren also made appearances. Wordsplayed collaborated with Mineo on the hit single “Martinelli’s” that they released in late December.

Established artists who do not frequently collaborate with Christian rappers also found themselves in the studio with Mineo. For those unfamiliar, here is a quick introduction.

Illmind

Super producer Illmind isn’t new to Christian hip hop. In 2004, he produced the song “Nobody” on Braille’s album Shades of Grey. The following year, he produced the whole album The Art of Onemind with Symbolyc One, who Rapzilla.com recently interviewed at SXSW 2015.

The vast majority of his production credits, though, have come working with artists not associated with Christian hip hop. Over the last few years, he’s produced songs for J. Cole, Kanye West’s G.O.O.D. Music and 50 Cent. His long list of prominent collaborators also includes Common, Scarface and KRS-One.

Illmind spent all four days in the studio with Mineo and company, so he should play a large role on the upcoming Reach release.

Jon Bellion

New York-based singer Jon Bellion showed up to the studio at least one day this week. He’s signed to Visionary Music Group, which is also home to hip-hop artist Logic.

Bellion could contribute to Mineo’s album as a featured artist, writer or producer. At the top of the 24-year-old’s resume is songwriting credit for Eminem’s song “The Monster” featuring Rihanna and Jason Derulo’s “Trumpets,” both of which went platinum. Bellion produced “Trumpets” as well.

Last year, Bellion told Interview Magazine, “I recently became a devout Christian. I’m fascinated by Jesus and pray to him every day.”
