What is the name of the ska band active in Omaha in the mid-90s & similar to Fishbone?
This is honestly a shot in the dark on my own part, as there isn't a great resource to look at the recent history of Omaha bands, but the band you're describing sounds a lot like the Confidentials. They have had some personnel changes but are still going strong. You can find out more about them at their website, including Facebook and Twitter links as well as email and phone contacts.
Does this sound right? Please let me know if you think it was someone else!
