“Petals” is Nicholas’s first solo piano album. The concept of the album is that each track choreographs a petal falling from a dying flower. “Petals” also represents Nicholas’s style of composing for piano. He has been developing this style since the first composition he ever composed, back in 2008. It is exemplified by repetitive movement that builds on itself, as well as a lot of internal voices that interact and compete with one another.
