I wanted to ask you, if you have any good references (book or pdf) to learn about the KK theroy of Kasparov. I think the presentation of Blackadar is too close from the commutative theory. 


I was searching for a C\* proof of the Bott periodicity and arrived [in this thread](https://mathoverflow.net/questions/131763/the-right-c-algebraic-proof-of-bott-periodicity/131797#131797). I searched in the references mentionned there but I didn't find anything about KK theory.


Any advice ?


Thanks :)



reference for KK theory
If you want to learn more about KK-theory there is a book by Kjeld Knudsen Jensen and Klaus Thomsen with the title "Elements of KK-theory". You can have a look there.


I would also recommend those surveys:
