The Of Montreal frontman, who established Blikk Fang as a side project with MGMT's Andrew Van Wyngarden, told BBC 6music that the tracks are old demos that the pair recorded individually.
He said: "It's total garbage, it's a total lie, those songs aren't even Blikk Fang songs. The one song is a Misfits cover that I did as a B-side four years ago, which is nothing to do with Andrew, and the other song is a demo he made in his dorm room three or four years ago."
Barnes said that the duo want to focus more on Blikk Fang over the coming 12 months, adding that conflicting schedules are proving to be the main obstacle.
"It has been hard because we both travel so much and we're both so busy with our own things. We're slowly putting something together," he said.
