Sufjan Stevens, "Particle Physics"

Asthmatic Kitty Records is an independent record label that was co-founded by Lowell Brams and his stepson, singer-songwriter Sufjan Stevens, in 1999. Since its founding, AKR has released albums by a variety of artists, including Lily & Madeleine, My Brightest Diamond and Helado Negro, and is currently home to Sufjan Stevens, Angelo De Augustine, Denison Witmer and The Welcome Wagon. 

Asthmatic Kitty was named after Sara, an orange and white tabby who wandered out of the woods pregnant and starving near Holland, Michigan in 1994. For fourteen years she brought joy as a beloved friend to Lowell, enjoying a happy life despite her initial hardships. Her asthma improved after moving west to New Mexico and Wyoming, where she lived out her days as an asthmatic kitty in name only.
