[LAU] "band in a box" solution for linux?

[Rusty Perez]

Hi folks,
The question earlier today about a stage worthy multi-track backing
track solution made me think of "Band-In-A-Box" a windows tool for
creating style bassed tracks. I also have an OLD!!! Roland arranger
keyboard which does something similar.
Is there an equivalent program for Linux which has banks of styles,
and you input chord sequences to be played by the "band?"

Thanks!
Rusty
