sunny september. One of the rare moments I'm
proud to live in Poland
coolasianbrian: me too!
fobfreako: I am currently learning this on piano for my
exam next year, but I'm having some difficulty
:(
This pushes me to keep practicing and not to
give up on it, because of a possible result as
beautiful as this.
Thank you.

brandon71085: Stand up's don't have the proper pedals. At
least the stage piano pedals have all the
abilities of a grand.
akissgr1: I think the piano cudus is been using is just
amazing really good sound and the reverb
really compliments all the songs well better
than any stand up piano.
RakkSemilath: klasse!!!

LEBURNTHEVOICE: almost perfect man,
but i guess you spent lots of year playing
piano,
