THERE is not a lot this band won't do. Their motto being to ask for forgiveness, not permission.

Lead man Kane Dennelly is behind the three man blues band, 19-Twenty who thrive on causing a rukus on stage.

"We have this theory, ask forgiveness not permission," Dennelly said. "We don't check if it's okay until after the event 'cause then we can't get in trouble.

"People forget we're entertaining ... all we're doing is playing music, make people forget their problems and not take themselves too seriously."

With Dennelly on guitar and vox, John Gwilliam on upright bass and Syd Green on drums, the band was created about four years ago through pinching members from other bands.

"The band's base on thievery," Dennelly said. "I was looking for drummer and saw Sid play with a mate and stole him then saw John play with another mate and stole him."

Having played in every state across Australia and numerous pubs and festivals, the three best mates don't plan their performances, instead feed off the crowd's vibes.

It is the audience jumping around and jumping on stage that keeps the tempo up according to Dennelly, but it has caught the "psycho blues" band out before.

"At Mitchell Creek we had 40 people jumping on stage and the stage was bending, it was covered it mud," he said.

"We've been politely asked a couple of times not to get the crowd so riled up."

Having always dreamed of being a musician, Dennelly said the music he first performed at 17-years-old was something lame he wrote about a girl.

"It would make me vomit now," he said. "Now (our music) is definitely lame, but not as lame. We try to have a bit more depth.

"We have songs about reading lots of bible passages then we have a song about getting drunk and dancing."

Dennelly said the band's music is blues with a rocky, crazy edge full of loud tunes but it is the boisterous jest on stage that intrigues the audience just as much.

"I talk a lot of shit on mic, I shouldn't but I do," he said. "People get up on stage ten beers under and dance and it's hilarious.

"But nothing in this world beats the energy of the crowd cheering, there's nothing that compares to that," he said.

19-Twenty will be performing from 6.15pm Saturday night at the Agnes Blues Roots and Rock Festival.
