Curtis formed School of Seven Bells with vocalist Alejandra Deheza in 2007, releasing three full-length albums -- the last, "Ghostory," coming in 2012 and peaking at No. 8 on Billboard's Heatseekers Albums chart.
Previously, he was a part of Dallas-based rockers Secret Machines, which found critical acclaim in the mid-2000s with 2004's "Now Here is Nowhere" and 2006's "Ten Silver Drops," the latter of which hit No. 159 on the Billboard 200. In the late-1990s, he was a member of the alt-rock group Tripping Daisy.
Since his cancer diagnosis in February, multiple musicians had rallied around Curtis, Pitchfork notes, including Interpol's Paul Banks, the Strokes' Albert Hammond Jr. and Devendra Banhart, who helped raise funds to cover treatments.
In October, Filter Magazine published an article containing words of support from Brian Aubert of Silversun Pickups, the Polyphonic Spree's Tim DeLaughter and more.
