I'm a fan (and you should be too) because... I got acquainted with Miles Davis genial "cool" master jazz musical work at the age of twenty one .I was fifteen years old when "Bitches Brew"  was first realised, Miles' was forty four years old then. Means that my first knowledge of Miles' was in his "Electric Period - Rock, Funsion, Funk 1968-1972". No other musical work of the 1970's couldn't had inspired, shocked, shook, and moved me as much as his work did... ~An exceptional,unusual,atypical,and unpredictable work of those times [1970's].
The next was history as the years goes by I became more familiar with the "Kind of Blue period 1955-1967": The Birth of Cool ; Miles Davis Kind of Blue ; and Some Day My Prince Will Come . ~By that time as his own work branded it was "cool", genial, admirable, cordial, and reverent! Even Miles' fashion was elegant, chíc, and formal! As also his scenic stage proyection was cool, calm, self-controlled, and extremely masculine!
But Miles' had more surprises to offer to the world. It then came the "Scetches of Spain" Period of 1957-1968". My grandfather was an emigrant for Barcelona,[Catalunya], Spain. He used to play the spanish acoustic guitar and delighted us with his spanish tunes. But what was never unimaginable was that a black jazz american trompet player could enchanted the whole world with his trumpet virtuosity performance of "Concierto de Aranjuez" [Adagio] [Joaquín Rodrigo 1939]. ~Miles' by then was captivating, venturesome, subjugable, astounding, and irresistable!
Then came his late works period "The Man With the Horn and Beyond". With much more contemporary tunes of the mid 1980's like, "Human Nature, and "Time After Time" , and albums like "Tutu" [1987 and "Decoy" . Pretty much ahead and beyond the traditional jazz standards of the times [mid 1980's].
Miles' talent at his ending years was still fresh, brillant, shinning, flamboyant, and vivacious! Miles'geniality was endless! His masterful late tours show performances, and his extremely eccentric obsessive narcissist fashions, were something "out of this world"!
What I still missing from Miles' is the "Second Great Quintet Period [1965-1968]". Due to work absorbing time I couldn't had the time to study it. But now that I'm on my retirement years I'm finding the plenty of time need it to examine his "Second Great Quintet Period". Which I'm not so familiar with it, and I'm not such dare to testify of it.
With this brief testimony of myself I clearly give you a whole big screen picture of the reasons and motives which I became in love with Miles' and his black american musical legacy.
