Grampall Jookabox's name sounds like its music -- it's at first convoluted, but then the rhythm takes over. The name stems from singer-songwriter Dave Adamson making fun of the way bandmate Aimee Brown mispronounced something, and then it expanded.

That's how the music also is born -- written first as a flittering melody or rhythm, then layered with plinks and plunks, harmonies, spoken bits and more. The way Adamson describes it, this creation sounds more like a process of experiments than the crafting of a whole song.

"We just started thinking about things differently and experimenting a lot more," Adamson said.

The result is the band's first album, "Scientific Cricket," released this week from Joyful Noise, an Indianapolis record label. This project marks a turning point for Adamson, whose previous band, BIGBIGcar, marks its last performance at the Grampall Jookabox CD release show.

"People seem to keep saying that it grows on you," Adamson said. "I like that, because whenever I hear something I like immediately it fades away."

The band's sound is singsongy and playful -- sometimes the lyrics sound like nursery rhymes, bells and a kazoo make an appearance, and the rhythms could be children banging on sticks as well anything else. Percussion is a heavy player in the Jookabox sound, Adamson said.

"I think it's just because I was obsessed with rap music for a long time," he said. "My big cousin Chris loved the Fat Boys and Run D.M.C . . . I thought he was so cool."

It's easy to tell this record is by the same man (and sometimes other members) behind the BIGBIGcar sound -- Jookabox feels like a continuation of the first project, but with a slight folk influence Adamson attributes to listening to the American Anthology of Folk Music around the time "Scientific Cricket" was recorded.

"I just try to find things I am really excited about, and that blow me away. I never try to force it."

Adamson, who says he gets bored by bands that only play strictly what's on their records and bands that only improvise without having a root, said Grampall Jookabox shows will not be exact replicas of the album. Each performance might feature different people playing with him on different nights, while still staying true to some aspects of the album.
