Glen and Kaylee Harrison are the powerhouse that have taken the country charts by storm in the last year.

They're still flying high off their latest release, In Our Blood, and will return to Tamworth with a jam-packed gig list.

The pair will be one of the featured acts at Live and Loud at Toyota Park on Tuesday, January 23, from 7pm.

The free concert debuted at last year's event and is aimed at showcasing the best in emerging young talent.

"It was pretty amazing and definitely a highlight for us last year," Glen said.

"We're really looking forward to it again.

"It's been a great year. The album has been out for nearly two years and we've got a lot of mileage out of the songs."

Also on their featured list of 2018 Festival performances is a show entirely about siblings.

In Our Blood will be held at the Frog and Toad Listening Room on Thursday, January 27, at 7pm.

The event will be hosted by another sibling duo, Alex and Bec Crook with an appearance by the Dennis Sisters.

"It's a whole show with siblings," Glen said.

"It's going to be a great bit of fun and a little more intimate than Live and loud."

Glen hinted the duo are also currently working on some new material on the way.

"We've been getting a terrific response," he said. 

"I think in the next few months people can look out for something else."
