Hundreds of fans in Denmark were highly disappointed in singer Whitney Houston’s performance and reportedly walked out during a June 3 concert, BlackAmericaWeb.com reported.

The Copenhagen Post, a weekly newspaper out of Denmark, claimed numerous media outlets country-wide gave negative reviews to Houston’s performance, describing her vocals as “weak” and “out of tune.”

“She looked and sounded like a person who doesn’t have many years left to live,” critic Thomas Soie Hansen of the Berlingske Tiende Newspaper wrote, according to BlackAmericaWeb.com. “At the end of the show she looked like she was ready to explode.”

Houston has been experiencing a tremendous amount of criticism during her anticipated comeback. She cancelled a string of European shows in April after being hospitalized with throat and nose problems.

The Denmark show was in conjunction with her “Nothing but Love Tour,” which opened in February, marking her first tour in 10 years.
