Released in 2015, this immense 72 track collection consisted of 10 brand new tracks and a plethora of early demos and various other recordings. While his new album 'Rise' was being recorded and mixed, Carl found himself writing and recording further material which he felt did not belong on the new album but, nevertheless, deserved to be heard. He then thought about re-recording some old demo songs he had but found it difficult to choose which ones to record from his vast back catalogue. After listening to these old recordings, he became fond of how some of them still sounded. One thing led to another and 'Unreleased' was the end result. There are still demo recordings that did not even make this album.
