R&B singer D’Angelo has been hospitalized and cancelled the next three shows in his tour, including the House of Blues show in Chicago scheduled for Wednesday. Fans of the singer are not only awaiting a third studio album to follow his 2000 release of Voodoo, but they might not see him hit the stage for a while either.

Due to a “medical emergency” D’Angelo has now racked up five cancelled shows since last week. The performer has left stages empty in New York, Maryland, Chicago, Minneapolis, and San Diego.

The Chicago Tribune reports that the promoters Live Nation said D’Angelo “expresses his sincere regret due to this unfortunate circumstance.” Though the medical condition has not been specified, it seems as though the singer will be alright.

D’Angelo’s agent confirmed that the singer will be fine, according to a House of Blues executive. The agent told him, “It’s serious but he’ll be OK.”

He has reportedly been in the hospital since he cancelled the Maryland show, according to a Facebook post from the Maryland Merriweather Post Pavilion.

It is not known if he will perform on August 9th for the San Francisco tour date, which is the only remaining show scheduled this summer.

D’Angelo, who has shied away from live performances in recent years, has scheduled more performances this year than in years past. The artist’s label has yet to set a release date for his upcoming album, which has been at least two years in the making.

Roots drummer Questlove told Billboard in January that D’Angelo’s album was “99 percent done” and well worth the wait. “I would not be far off by saying this is probably my generation’s version of Sly (and the Family Stone’s) There’s a Riot Goin’ On,” said Questlove.
