The style of piano master and composer XA4 is hard to define. That is because it is unique in it's kind. Acoustic piano is mixed with electronic extensions and soundscapes created with recorded samples from his old Bechstein grand piano. Influences in his music range from minimal and ambient to classical and electronic.

Xavier Boot, also known as XA4, started to play piano at a young age and soon showed prodigious talent. He studied classical piano at the Amsterdam and Düsseldorf conservatories and did a master in live electronic music. Xavier won various prizes for playing piano in his home country the Netherlands and he also composed music for prize winning films. Xavier has a Dutch-Indonesian background and gets inspiration from Gamelan music for his compositions.

Xavier released work with record label Excelsior in the Netherlands and in 2022 signed with the American label Orange Mountain Music.


Xavier lives and works in Amsterdam.
