Myspace secret shows: MySpace Secret Shows is a free concert series where MySpace users are alerted that a band is playing a free show through a series of blog posts and bulletins.  These bulletins and blogs are sent out from both the artist's page and the official MySpace Secret Shows' profile two or three days before the show.  The series began on January 29, 2006 when Jenny Lewis of Rilo Kiley played at the Hotel Café in Hollywood.  The opening act, The Elected, was fronted by Lewis' bandmate Blake Sennett and at the end of the evening, the two played a handful of Rilo Kiley songs.

Agitation Free: Agitation Free is a German experimental krautrock band, formed in 1967 by Michael "Fame" Günther (bass guitar), Lutz "Lüül" Ulbrich (guitar), Lutz Ludwig Kramer (guitar) and Christopher Franke (drums).  They were initially called Agitation, a name they chose at random from a dictionary.  The band had to change the name because another band with the same name already existed.  Agitation Free was chosen based on a poster for a free show played in the early 1970s saying "Agitation Free" (meaning "free concert").

Jacobs Well Theatre: The Jacobs Well Theatre was a playhouse in Cliftonwood, Bristol, England, which opened in 1729.  It took its name from the nearby Jacobs's Well, which may have been a mikveh, a type of Jewish ritual bath.  The theatre was built by actor John Hippisley, who had created the character of Peachum in the premiere of John Gay's Beggar's Opera.  The stage space was so small that actors exiting on one side had to walk around the building to re-enter on the other side, often being subject to banter by spectators enjoying this free show.  A hole was knocked through a party wall to an adjacent ale house, The Malt Shovel, so that actors, and audience seated on the stage, could obtain refreshments.  Admission prices ranged from 1 shilling to 3 shillings, and it was estimated that a full house could earn as much as £80.  Servants of patrons were admitted free of charge to an upper gallery.  In later years, Thomas Chatterton described the theatre as a "hut".
