Finally listened to In Concert after I don't know how much time. Indeed, the sound is not that good. But one gets used to it after a while. Either that, or the sound actually improves, I don't know. Good call about “Chieftain” being the actual tune which starts the show and then segues into “Rated X”. Speaking of the latter, this is actually the first time the world heard this tune, the studio version having not been released yet in any form. I can't say that this version has anything going for it except the fact that you can hear Miles playing some trumpet on it, which does not happen at all in the studio version. I really began liking the album during “Jack Johnson” – when Miles does that little melody at aboout 8:30 you can cleary hear a band enjoying themselves. They are cleary are having lots of playful fun. Big fun, so to speak. Both “Ife” and “Right Off” are good listens, but, no, I'm not necessarily impressed.
