None of those technical masters could step into a blues gig and play world class level blues. Who is the greater builder of structures, a master stone mason or a master brick layer? That's the comparison you are making. Two separate specialties with different requirements, both of which have trade secrets the other has little or no concept of. So your comparison doesn't make any sense. It leads me to conclude your blues listening has mostly been superficial and/or you just don't appreciate the genre, which is ok too. I'll stop pushing my record on you.
world class level blues? like what? like who? T-Bone Walker? Muddy Waters? Tampa Red? Lightnin' Hopkins? Willie Johnson? Son House? Howlin' Wolf? George Benson? I heard much of it, and it was great at first, but my interests expanded into what was new and innovative, and "happening now" throughout my life, and some still stay in place - like The Beatles, Small Faces, Yes, Sabbath, The Cure, The Smiths, Death, along the way. The only things I still listen to today that is even close to blues is Hendrix, Small Faces, Humble Pie, or some of the blues rock bands like LZ.
blues, maybe something before 1960 perhaps, when it was new innovative and fresh, not a well-defined constrained structure that it has become since the mid-70s
I like old blues, but I find other genres more interesting; and when I hear "modern blues" it bores me, as it's not even close to blues from the 70s and earlier.
I liked big band, motown, blues and rock when I was a tween and younger , then as I got older getting into prog rock, punk, hard rock and new wave, and into thrash, death metal..as a progression. I listen to some old stuff from many genres because I grew up with it / nostalgia vs more complex music I enjoy today.
The music we like is subjective; but the complexity and skills can be assessed objectively. Who would compare Mozart to Taylor Swift?
edit: there are a few songs I remember hearing on the radio when I was a small child;. I still remember the first time I heard them, usually in the car, or at my teenage uncles pool parties...songs like: "Baby Love", "Yellow Submarine" , "Monday, Monday", "Good Vibrations", "Paint it Black"... and an older song, "Sherry" - which I remember because I had a childhood friend named Cheryl, that everyone called Sherry...some songs just stay forever, not all do. I had a small mono record player, and whenever I heard a song I liked on the radio, someone would buy the 45...I had a stacks of them, and wore most of them out...and apparently drove my great grandmother crazy playing songs over and over...Cheers!
