There's more than one Organic Tour. One, with the Gastrobus, goes to farmers markets. The one coming to The Altamont Theatre on Friday, Jan. 25, is not about food. It's about laughs — specifically those provided by comedians Jarrod Harris (of Comedy Central) and Ryan Singer (recently mentioned in Rolling Stone). The two are traveling the country in Harris' RV, working on a documentary and performing. “This tour will showcase the freedom of the art form that these venues allow, and the people who have unwittingly created a place for comedians such as Jarrod and Ryan to come into their own before breaking through to the next level," says press for the event. "This will be funny, weird, experimental and, most of all, organic.” 8 p.m., $12. http://myaltamont.com.
