Visconti, 72, who worked with Bowie on his final LP "Blackstar," which was released a few days before his death, said the "Lazarus" singer was not comfortable in playing guitar in front of professionals, reported Femalefirst.
"He was great. He plays some of the rhythm guitar on a lot of the tracks on 'Blackstar'. And a little lead guitar, but he did it at home. He felt intimidated about playing the guitar in the studio.
"One of the reasons why he worked with me was because I was an old friend and he could just take all the time he wanted in the studio. But if there were too many professionals in the room, he felt like he wouldn't play well," Visconti said.
"He told me on the phone that he couldn't wait to get back in the studio again. I said, 'I'm on tour with (Bowie tribute act) Holy Holy, but wait till I'm off tour.' David said, 'Righty-ho!' That would have been happening in February."
Bowie died in January at the age of 68 following a secret cancer battle.
