In October 2018, it was revealed that an Amy Winehouse hologram tour was in the works for 2019. Now, BASE Hologram, the company that was developing the project, announced this week that the tour has been put “on hold.” The company said in a statement that the tour is being pushed back after they encountered “some unique challenges and sensitivities.” Find their full tweet below.

In an additional statement sent to Billboard, BASE Hologram chairman and CEO Brian Becker said:

“Sometimes in developing this type of highly ambitious, state of the art hologram/augmented reality theatrical event we encounter some unique challenges and sensitivities that cause us to take a step back. Developing our productions is a cross between a Broadway show and a concert spectacle which requires creative engineering and that type of creativity does not necessarily follow a schedule. And that’s what happened with Amy Winehouse, we promised to celebrate her life in the most respectful way possible—as we did with Roy Orbison and Maria Callas—and to ensure we keep that promise we are putting the tour on hold while we plot out a creatively spectacular production fitting of her remarkable career.”

The tour was slated to feature Winehouse’s hologram backed by a live band, singers, and theatrical stagecraft. Last year, Winehouse’s father Mitch told Reuters that all of the tour’s proceeds would benefit the Amy Winehouse Foundation.

Amy Winehouse died in 2011 at the age of 27. A biopic centered on the late singer is currently in the works. A posthumous vocal from Winehouse was recently featured on a new song by Salaam Remi and Nas. Read Pitchfork’s Afterword feature on Amy Winehouse.
