I've just recently finished writing and recording a three movement piano concerto. I performed all the instrument parts on my Roland digital piano. I am a self-taught musician, playing the piano, guitar, and harp.*
The concerto took about three months of hard work from start to finish.
I have uploaded all three movements to the following website, and they can be streamed there:

I hope you like my music!
