Sometimes part of the fun of going to a music festival is piling into your mom's hatchback with five friends, hoping you'll make it all the way to Indio, Calif.; Austin, Texas; or even Manchester, Tenn.

Bröötal Sun Fest, a music festival now in its second year, offers the adventure of discovering 50 independent rock bands in downtown Tucson over the next four days.

"None of these bands have a large draw, but it's a very diverse group, and we're really excited to get them," said Logan Greene, the festival's founder.

The second annual Bröötal Sun Fest kicks off tonight at Skrappy's and Dry River.

The festival includes local acts - such as Doctor Dinosaur, Jaime J. and Steff Koeppen and the Articles - and about 30 bands from different parts of the United States, along with two from Canada.

The Phoenix-based Andrew Jackson Jihad is headlining the festival and will play Sunday night at Skrappy's.

The punk-folk group resembles the Boston rock heroes of Dropkick Murphys, but without the big-band sound. It has released 19 recordings since forming in 2004.

Greene, 22, carefully crafted the festival's lineup.

"We handpicked all 50 of the bands," said Greene, who plays guitar for Doctor Dinosaur and for Logan Greene and the Bricks. He's also Dry River's booking director.

The music ranges from garage-punk, such as the Shrapnelles, to the charming acoustic folk of Watercolor Paintings.

Greene was inspired by the Crucial Fun Fest in Lexington, Ky., which he played with his band Doctor Dinosaur.

"I started to create something as unique and awesome as that. The bands were really supportive of each other, and nobody was there for any reason but to see the bands and have a good time," Greene said.

He selected venues that didn't hinder or limit the concerts.

"I like to keep it all-ages," Greene said. "I've been going to Skrappy's since high school, and they put music first. This way people come for the music instead of drinking and socializing."

Last year's festival had about 45 bands and sold about 125 tickets. Greene hopes to double sales this year.

The festival is a "do-it-together" event with an all-volunteer staff and proceedings going to the touring bands and nonprofit venues.

"There are no sponsors or contributors - just a bunch of independent people who enjoy music," Greene said.

The music will alternate from Dry River in the afternoons to Skrappy's at night.
