Disappointing news for those fans hoping to check out the return of the SnoCore Tour this year, as it has been called off just a couple of days before it was set to kick off.

Unfortunately, Taylor Momsen, lead singer of headliners the Pretty Reckless, is battling walking pneumonia and acute laryngitis, forcing the band to pull out of the tour. As a result, the entire trek has been canceled.

The SnoCore Tour, which was slated to return after a four-year absence, was also set to feature Heaven’s Basement, the Letter Black, Crobot and Empire Street. No word yet if those bands will make alternate plans to tour the United States. Snocore had been scheduled to run from Jan. 29 in Lincoln, Neb., to Feb. 23 in Los Angeles, with a Feb. 4 stop in Flint.

Momsen has been ordered on vocal rest, but the Pretty Reckless' upcoming album, 'Going to Hell,' is still slated to arrive on March 18. The disc features the current single 'Heaven Knows' and the title track.
