If you aren't used to the conversation it sounds too foreign to be appreciated. You'll likely have had the experience of being around foreign language speakers, some you'll be more comfortable with than others even though you don't understand a word that are saying. Think Manga with the subtitles on or Italian opera. So it is with musicians and their jazz conversation. It takes a lot of experience and listening to really feel the jam and synchronisation. It's very rewarding if you put the time in. Took me ten years or so mainly invested in just three lauded jazz albums.
