Inna, which Coltrane? He seemed to always be in constant change. I don't think you can just have a couple. You need them all. 😉
Personal favorites would be Live at the Vangard, Giant Steps, Favorite Things. Of the latter "louder" period, take your pick, all good in their own way, although a harder listen. Enjoy the journey!
Oh yeah, The one with Johnny Hartman is really good!
