your favorite artists collaborating

[Lord Valtasar 12,690]

sometimes,your favorite artists surprise you and collaborate with eachother,and when you have no prior information of it,its the best feeling ever.
for me it was when Avantasia and klaus meine(scorpions) made a song togather(dying for an angel) and when i first discovered ayreon albums(which have plenty of my favorite artists)
and for books,when i found out that Brandon Sanderson will finish the Wheel of Time series

so what was yours? it can be any sort of collaboration not just music
