You’re new? You’re not? Either way, having chops is all it takes. Anchored at the roomy yet cozy Cabaret Jazz at The Smith Center, this is a terrific monthly (more or less) outlet for established talent (Clint Holmes, Jersey Boys stars, visiting Broadway vets) to work out fresh material, and for newbies to get connected with the local scene. The vibe is loose, the audience is a cool mix of local celebs and plain old aficionados, and the good times can approach greatness. 702-749-2000, TheComposersShowcase.com.
