Sucks to be fired, but this situation may possibly have pointed out something that you could use to your advantage. Sometimes some players can get/be 'to' specialized. This would be a great opportunity for you to branch out your playing some and learn some different styles outside of just blues. It's inevitable that in the future there's going to be other people you play with who wish to stretch out a bit and dabble with things outside of blues. It sounds like you're not that comfortable playing things other than blues, so when it comes up it's a comfort and style issue for you. I'd take this down time as a good opportunity to spend time playing some of those other genre's that are loosely tied to blues. R&B, Motown, Classic Rock, etc. Definitely not saying you need to go learn to slap, etc. But being relatively 'confident' in loosely related styles is ALWAYS a plus in the long run. IMHO. .
