Moroder, 74, said he has prepared a number of tracks for Gaga's upcoming yet-untitled album, reported Guardian online.
"I was supposed to be in the studio with her a week ago, but I got a cold. I'll see her when I'm back. I have about five or six tracks, just basic ideas. Drums, keyboard, bass. I'm going to be surprised, I think - I don't have a clue about the way she's recording. Will she play the piano? Will I?," he said.
Although this material is intended for the follow up to Artpop, Moroder also stated that he would like one of the songs recorded in these sessions for his own album.
