As said in my OP, Kendrick Lamar’s “To Pimp a 🦋 Butterfly” is as sophisticated musically as any music I know. The musical themes evolve and develop including a brilliant rhythmic rap and sound effects that create “deep and broad emotional and intellectual content”. If you check it out keep an open mind and judge it in its entirety. I think you will find it interesting if not gripping. In my superficial and introductory dive into Rap, it is firmly in the genre yet unique.
So, over the weekend, I had a chance to listen to most of it.
jssmith207 did a pretty good run down.
The sax player, Kamasi Washington, and the bass player, Thundercat, are good players, and I have recordings (non rap) with them, which are quite good.
And while I can say, this album might be creatively a step up from most rap I have heard, it still has all the drawbacks of the genre I have a problem with. Simplistic song structure, unsophisticated harmonies, mediocre musicianship (even though Kamasi and Thundercat play on this album, they don't do anything their skills require), repetitive, etc. Sure, there is some real creativity here, just not in the realm of composition and musicianship.
Sorry if this sounds insulting, but rap, even this recording, is about as musically simple as music can get. Even, with the various layering, sound effects, and overdubs, etc.
Seriously, there are genres and subgenres of music, with ridiculously complex time signatures, complex chord progressions (and more than 3 or 4 chords per song), with very little or no repetition, with musicians that have otherworldly levels of musicianship, and they are still able to convey deep and broad levels of emotional and/or intellectual content, even with no lyrics at all.
