Grindmother at the Phoenix Theatre in Petaluma, California in 2018.

She has been performing since 2015 with her son’s grindcore band. She is almost 75 years old

In Windsor, Ont., in 2015, Rayny Forster’s mother was messing around with her son’s grindcore band.

Grindcore combines hardcore punk and aggressive guitar riffs, and the lead singer usually screams words that are hard to understand.

Rayny’s mom took the mic, yelled out some political lyrics, and started to like the style.

Forster recorded that session, and the video that came out of it went viral. It was the start of a whirlwind two years of interviews, recording, and touring for the 74-year-old grandmother, who has kept her real name secret and goes by the stage name “Grindmother.”

Now, Grindmother wants to get back into the game.

Right now, there are a lot of things to scream about. The way things are going on Earth… There are a lot of unfair things.”– Grindmother

The last time Grindmother performed was five years ago.

Grindmother and the band of her 44-year-old son put out a 10-song album together.Age of Destruction, in 2016.

“I’ve missed it while we were taking a break,” said the former social worker, who will turn 75 next month.

Between 2016 and 2018, she went on a tour with her son that took them to Canada, the U.S., Japan, and Germany.

The lyrics talk about wrongs in society

“There are a lot of things to scream about right now, which is one of the things that inspires me,” said Grindmother.

This month, she went to London, Ontario, to see her son, who now works for a cannabis company there. 

“There are a lot of things that aren’t fair, like how the world is going, how there are bombs and wars, and how there isn’t enough food for everyone.”

When Grindmother screams, she thinks about all of these things. Some music,Mother Nature, Begins with the words “Mother Nature deserves our respect. Instead, she is getting hurt.”

Grindmother, who now lives on Manitoulin Island, celebrates her 75th birthday this August.

Grindmother, who now lives on Manitoulin Island, said, “We care a lot about things being fair and getting our message out there.”

I think it’s great that she has the courage to go out and do this.Rayny Forster is the son of Grindmother.

“I like being up there with her,” Forster said. “I’m really proud of her for being brave enough to go out and do this, and not just make a few songs but also tour and do everything else.

“It’s pretty much a whole way of life.”

Forster did admit, though, that living in a tour van with your mom is a little hard.”It’s all part of the fun,” he said with a laugh.

Grindmother is originally from Windsor and now lives in Manitoulin Island. She's celebrating her 75th birthday this August.

Tough on the vocal chord

Forster said that grindcore is all about “making loud noises.””A lot of the time, it really sounds like a guttural growling.” 

Grindmother said that can be hard on a person’s voice.

She said, “I have to be very careful, and I have to force the air through my throat so that it doesn’t tear it.”

“Once I figured out how to do that, I stopped getting a sore throat all the time.”

The mother and son duo hopes to put out a song in the next month or two. If everything goes as planned, they’ll be back on the road touring soon after.
