The 'ween scene

Occasionally, Halloween falls on a weekend - as with this Saturday. This means you can stay out later and live it up in heartier fashion.

And for post-trick-or-treating (or even Friday), there's no reason not to avail your costumed self of the many musical opportunities presenting themselves.

Herewith are some fine sonic options with holiday overtones:
