One of rock 'n' roll's great outsider voices has canceled his performance in Asbury Park this spring.

Acclaimed Austin, Texas-based singer/songwriter Daniel Johnston will no longer perform April 20 at the Paramount Theatre on the Asbury Park Boardwalk as part of the 2017 Asbury Park Music and Film Festival, it was announced Wednesday.

Johnston, whose performance at the Paramount was to be the opening night event of the festival, will not play due to medical reasons, said James Wark, the executive producer of the festival.

“We're all hopeful he'll be well soon but it's simply too early to determine if he will be well enough to perform at the festival,” Wark said.

Johnston was to be supported by the all-star backing band Summer Moon, which includes Nikolai Fraiture (The Strokes), Stephen Perkins (Jane's Addiction), Camila Grey (Uh Huh Her) and Noah Harmon (The Airborne Toxic Event).

Johnston, a famously eccentric artist and musician originally from West Virginia, has had his work covered by the likes of Tom Waits, Wilco, Beck, The Flaming Lips and Death Cab for Cutie.

Johnston's troubled history was chronicled by Hazlet native filmmaker Jeff Feuerzeig in his 2005 Sony Pictures Classics documentary "The Devil and Daniel Johnston," which earned Feuerzeig documentary directing honors at the Sundance Film Festival. That film will also no longer screen at the Paramount Theatre on the night of Johnston's performance as part of the festival.

Presented by founding Partners RWJ Barnabas Health and the Asbury Park Press, the 2017 edition of the Asbury Park Music and Film Festival is set to feature performances by Robert Randolph and the Family Band, Preservation Hall Jazz Band and Me First and the Gimme Gimmes.
