Sharing his own tribute post on tumblr, Stevens wrote: “He was a bright star, a good friend, and a great musician. It was always such a joy and a fierce spiritual journey to work with him. Heavy hearts and deep sorrows over here. Ray, may your soul glimmer brightly on the other side! And may perpetual light shine upon you. I love you.”

Raposa was born in Michigan City, Indiana, on January 22, 1981. He started out as a free-jazz musician in a band called Womb, before travelling the US for four years via Greyhound bus from the age of 15. In 2002, his collaboration with Nathan Delffs ‘What Kind Of Cure’ caught the attention of Sufjan Stevens, who signed Raposa to his label Asthmatic Kitty.

In 2004, the pair moved to Brooklyn, and Raposa released his first album ‘Cathedral’ under the Castanets moniker. He went on to release five more records as Castanets over the next ten years; 2005’s ‘First Light’s Freeze’, 2007’s ‘In The Vines’, ‘City Of Refuge’ in 2008, 2009’s ‘Texas Rose, The Thaw And The Beasts’ and ‘Decimation Blues’, his final Castanets project, in 2014.

He ventured outside his Castanets moniker for 2012’s ‘Little Death Shaker’, releasing that under the name Raymond Byron and the White Freighter. He released his last album as Raymond Byron earlier this year, titled ‘Bond Wire Cur’.
