Zenteno in better days at Sambuca: Mayra Beltran/Chronicle

UPDATE: From Norma Zenteno's Facebook page: Apparently there are some rumors out there that Norma has passed away. That is not the case; she is still with us! She is on life support but she is still with us. We will provide more information about her condition as it becomes available.

Norma Zenteno, one of Houston’s most enduring performers and part of a musical family dynasty, is near death, according to her family.

A family member, who does not want to be identified, says Zenteno is in a "Houston-area hospital" and in a medically induced coma.

This was posted to her Facebook page:

"The prognosis is not good for Norma. The doctors have advised her family to be prepared for the worst and Father Sal will be visiting and blessing her today. There is always hope for a miracle and we continue to hope and pray for one.

The Norma Zenteno Band which includes her brothers Javier, Bobby and Ernie has regular Thursday night gigs at Sambuca’s on Main & Travis in downtown Houston. The band will be performing tonight in honor of Norma.

Please continue to keep Norma and her family in your hearts and prayers. We will provide you with more information as it becomes available."

Zenteno announced she was battling Stage 2 breast cancer earlier this year on her Facebook page. She started chemotherapy this month and was having a “rough time.” Her kidneys started shutting down Wednesday, and she went into cardiac arrest early Thursday morning but was resuscitated.

The fiery singer effortlessly mixes Latin, jazz and rock in both English and Spanish.

Zenteno married longtime boyfriend Stephen Shaw last month at St. Patrick's Church on Houston's Northside. She was previously married to guitarist Mark Towns and computer technician Stephen Shaw.

Roberto Zenteno, Norma's father and a Mexican trumpet prodigy who led big bands in Houston for five decades, died in 2004. His daughter carried on his legacy, and despite early acclaim for her sound and chances to take it national, seemed happy showcasing it for fans in Houston.

"I've always been very comfortable with where I am. It makes me angry when people come up and say 'You should have done this' and 'You should have done that.' The important thing is for me to be happy," she told the Houston Chronicle in 2002. "I've had offers, but they weren't right for me at that moment. If something bigger happens, cool, but I could stay where I am right now and be happy."
