According to Chicago Band, Travis Scott has tried her song without loan or permission

A Chicago band said that one of the largest rappers in the world used part of her song on his new album – but Travis Scott had not credited, compensated or deleted the sample.

After working and applied for years on her song “Pursuit”, the Chicago band Pixel Grip woke up to a surprise when they heard an example of their song.

“And then I listened to it again and then it was in all caps like 'Holy S ***!'” Said singer Rita Lukea.

Lukea told her bandmate – drummer/producer Tyler Omen and synth player/producer Jon Jon Freund, her song was on the new Travis Scott -Album “Jackboys 2.”.

“I can just say it immediately, because I worked so hard on this song. It's like I hear the bass line in the background. I can hear the noise that swirls at the beginning,” said Freund.

Pixel Grip played her song “Pursuit” and Travis Scott's song “Kick Out” next to each other and said there is no doubt.

“As soon as I had headphones, I was like Yo, you, that's just a rehearsal,” said Omen. “This is the song in the background.”

The Pixel Grip Song “Pursuit” took years – began in 2018 at a festival. The band's media will show clips from them in 2020.

So the band posted online that the Travis Scott song “persecution” had tried without permission.

“I just can't stop thinking about who knows extremely famous or powerful about us and even likes our music, but refuses us to throw a bone,” wrote Pixel Grip in a post about X.

The Pixel Group said they had a message from Scott's co-producer Sean Momberger and told them: “Hey, the label should soon turn to delete the sample soon.”

Momberger said that the song was not clarified before the publication and added that he loved “persecution” and “knew that it was something special if [he] heard it. “

Momberger was also behind the probably largest rap hit of the last year – Kendrick Lamar “not like us”.

“It would only have meant the world if he just marked us or shouted out in any way, how it would have been a big moment for us,” said Lukea, “but instead he just behaved as if we didn't exist.”

When the band overlooks their new album, they say that they are open to working with others.

“We are happy to work together, just let us know,” said Omen.

But they hope to be part of the process – not just the end product.

“Song is good,” said Lukea. “We just want recognition.”

From September 23, the band will take to the streets for a tour with dozens of stops and is already thinking about how they will include the controversy in their sets.

CBS News Chicago turned to the producers Momberger and several members of Travis Scotts Team. We haven't heard yet.
