Great piece! The clarinet part sounds a bit muddy and distant and echoey to me though. The piano sounds clear and in the foreground. As for the music itself, your treatment of thirds in the beginning and when that idea returns throughout the piece reminds me somewhat of a piece I happened to hear in Jr. College for two pianos by Rachmaninoff. You do however bring your own individual spin on it with a unique rhythmic identity. I love the extended clarinet cadenza - like I mentioned though, to me it sounds like there's too much reverb. But if you're happy with it, no need to change it at this point since you've expressed that you want to move on to other projects. I do get a very nostalgic feeling when listening to this work which I think you said was your intent. Well done!
