Sean Daly from Tampa Bay.com wrote a great piece.
A quote:

I wound up covering a slew of Springsteen shows – including his Super Bowl stint in Tampa in 2009 – and the sound I remember from those gigs, the one that still resonates, wasn’t the singing or the drumming but that fallen-angel sax. It was edible, tangible – you could pluck the notes out of the air and take a bite.

Rolling Stone has Bruce’s statement:

Clarence lived a wonderful life. He carried within him a love of people that made them love him. He created a wondrous and extended family. He loved the saxophone, loved our fans and gave everything he had every night he stepped on stage. His loss is immeasurable and we are honored and thankful to have known him and had the oppurtunity to stand beside him for nearly forty years. He was my great friend, my partner and with Clarence at my side, my band and I were able to tell a story far deeper than those simply contained in our music. His life, his memory, and his love will live on in that story and in our band.

But the match was strong from the start, and his saxophone soon became a focal point of the group’s sound. In an interview with The New York Times in 2005, Jon Landau, Mr. Springsteen’s manager, said that during the recording sessions for “Born to Run,” Mr. Springsteen and Mr. Clemons spent 16 hours finessing the jazzy saxophone solo on that album’s closing song, “Jungleland.”
