Contemporary Classical Composers - new discoveries

Can we consider nuevo tango as modern classical music? I'm thinking of Dino Saluzzi and Astor Piazzolla 

Interesting question, @mahler123

Nuevo Tango itself was created by Astor Piazzolla which is mixed with jazz improvisation. I’ve mentioned Dino Saluzzi, but did not mention Daniel Binelli, who took it to the next level mixing Tango with African rhythms. Also he wrote tango symphonies and was playing-conducting those. Daniel Binelli is still alive and even well.

I've mentioned Hans Zimmer, because he indeed modern classical composer for the movie scores and so can be many more.

I haven't seen anyone mentioned Brazilian Choro composers such as Ernesto Nazareth or Heitor Villa Lobos... Can we consider them as modern classical composers?

My contemporary lineup:

Phillip Glass

Michael Nyman

Hans Zimmer

Sergey Rachmaninoff 

My first exposure to Michael Nyman was from movie score

"The Cook, The Thief, His Wife and Her Lover" by Peter Greenaway.

That was one of the most brutal movies I've ever seen.

Not really a new discovery, but how we can forget about Hans Zimmer?

Recently came across the band Bliss. It's ambient neo-classical crew that wonders me with every of their album. 

I see Phillip Glass mentioned many times here.

The only weird thing about Phillip Glass he bases all his compositions off the simple minor chord arpeggio
