Fans anticipating Nas and Santigold on the Portland stop of Lauryn Hill's Miseducation 20th Anniversary tour recently found out both artists were removed from the roster unexpectedly. 

Complex reports fans were also told shows on the tour were canceled due to "production issues."

Santigold, who was dropped from the tour Wednesday, informed her fans via Twitter with a series of tweets relaying information she learned about her impromptu removal:

Legendary rapper Nas has yet to make a public announcement regarding the latest news. However, reports from the St. Louis Post-Dispatch state he will not be performing at the upcoming October 5 show at Chaifetz Arena.

Amid the backlash, Hill, who has been accused of stealing music by former collaborator Robert Glasper, wrote an essay addressing such claims. 

"I’m confused as to why such a principled musician, who thought I ‘stole’ from his friends, would show up to work for me anyway. If that was hypocrisy or opportunism instead of genuine interest, it would further explain why an artist would feel the need to put his or her guard up."

Hill has not released a statement regarding the tour changes.
