I am happy to introduce you to my new favorite composer, Gabriel Kahane. Mr. Kahane has collaborated with Rufus Wainwright and Sufjan Stevens (amongst many others.) He's also been commissioned to do some really cool pieces too. Oh, and here's the link to his wikipedia page, so you can read up on him.
Take a few minutes to peruse the collection of his interview videos with Classical Chops...
Gabriel Kahane's 2011 release: Where Are The Arms
His pieces are gorgeous and complex - I just love music that has substance with layers like an onion.
You can even download his album "Craigslistlieder" for FREE! It's a pretty brilliant collection of songs written with lyrics made from anonymous Craigslist ads. Pretty hilarious and beautiful at the same time.
