The world went into shock last week after the unexpected death of retired NBA star Kobe Bryant, who was killed in a helicopter crash on Sunday, Jan. 26 alongside his 13-year-old daughter Gianna and seven other people onboard.

Before Bryant’s relationship with Nike, he had several signature adidas shoes, including the KB8, KB8 2, KB8 3 and the Kobe 2. Run-DMC also had a well established relationship with the company as well. With Bryant, who at the time enjoyed rapping, him and hiphop group were able to connect to make a song together.

Rev Run told Yahoo Entertainment, “Years ago, somebody connected [Run-D.M.C.] to Kobe Bryant, and we were going to make a record together. We met at the studio [in L.A.], because Kobe at the time had a relationship with adidas, and we had that big record, ‘My Adidas.,” he said. “So we hung out all night and discussed options of how we should make the record.”

Rev continued, “He liked to rap, we knew he was a good basketball player that wanted to rap with us, and we had a great night, took pictures. He was excited to meet us, and we were excited to meet him. It was just beautiful hanging with Kobe — and starting to record a record that we never finished.”

Rev Run says he is unsure where the unfinished track is located, but is almost certain it will pop up one day. “…Maybe it’s in the archives of some studio, or a demo that we made in our house that we was going to give to them to download their vocals. But somebody will find it,” he told Yahoo Ent.
