You know what’s all the rage right now? Band names inspired by nature. You’ll nary see a lineup quite as bucolic as tonight’s at the Presidio Yacht Club in Sausalito, wherein a flock of small-winged sparrows will magically fly through a gate and then above leaf-heavy trees, towards that rare occurrence of a moonbow.

Or maybe some bands will play some songs. The evening will begin with the mellower mountain folk of Sparrows Gate and Little Wings, then segue into the psych-rock of Magic Leaves and Moonbow.

Tickets are $5 for members and $7 for the general public. John Muir would approve.
