it sounds a little disjointed and messy; the guitar, or that other stringed instrument (not the piano) seems to be a little off-beat in the middle of the track.
the other stringed instrument is a mandocello! and i tried to record in as few takes as possible so I ultimately decided to keep the parts that i flubbed. personally, i like that it's a little unpolished and improvisational, but it certainly is a matter of taste.
Do you mean that others can add to this same page (and make it a collaboration page)?
yes! if anyone desired to, they could totally add pieces of their own! as long as the pieces match the general concept of "live show by random musicians in the library" it works for me!
Also, what software did you use to edit everything together, if you don't mind me asking?
for this first piece, i overdubbed tracks on ableton live, and the piano was the "Alicia's Keys" vst by native instruments. i used a little stock reverb and EQ, and that's about that.
