From a musical about the joys of cannabis to a production about the French Revolution that will roam the streets of Allentown, the Buffalo Infringement Festival contains some of the year's oddest and most innovative pieces of theater.

The festival, which kicked off Thursday with an opening party in Nietzsche's, will host several dozen theatrical or quasi-theatrical presentations, all of which are listed on the festival's website, Here are a few highlights of the festival's many theater presentations.

*Steve Roylance, writer of Road Less Traveled Blacklight's "Dependent, Undisciplined and Sleeping Late," will present his "City Sketches," a "slightly vulgar" collection of shorts drawn from life in the Queen City. The show is at 3:30 p.m. today in Westside Stories (205 Grant St.), 4:30 p.m. Saturday in El Museo (91 Allen St.), 3 p.m. next Friday in Main Street Studios (515 Main St.) and 3:30 p.m. Aug. 4 in Rust Belt Books (202 Allen St.).

*"420 The Musical," which had its first outing earlier this year, is a project in development by a local troupe known as the Francis Bacon Experiment.

Says FBE's Nick Russo: "It's fun, it's silly, and it's best if you pre-game it."
