Why does it sound so familiar to me?
Nice job.. Already nice sound when played loud... Maybe use some more ambient mics in the mix and some processing to make it a little more spacious and "louder" at average volume knob positions... It's a bit "dry" (not meaning as without reverb, but in a figurative way) as it is. But I like it overall... I imagine that some mixing and processing will make it more clear and lively and it will be a nice free jazz recording...
