Context: The International Olympic Committee (IOC) promotes women in sports in an effort to increase participation in the games as well recognition of the well being of women and girls in sports at all levels of sports and different structures within sports.  This is consistent with the Olympic charter which promotes equality within sports of men and women by including both genders in these competitions.  The IOC as well as the International Federations (IFS) and National Olympic Committees (NOCs) have been committed to the mandates of this Olympic charter.  Multiple measures have been taken toward increasing the participation of women at governing and administrative levels as well as training and education toward women in sport and the supporting administrative structures.  Since 1991, all new sports asking to be included in the Olympic program must feature women’s events.  The 2012 Olympic Games in London were the first Olympics where every participating country included female athletes.  They were also the first Olympics in which women competed in all sports in the program.  Women have competed in the Olympics since 1900, following an all-male Games in 1896.

Decibelle (formerly Estrojam) is a 501c3 NFP music and culture festival that promotes equality and was established in 2003.  Past headliners have included, Wanda Jackson (First Lady of Rock who toured with Elvis in the 1950s and 1960s), Nina Hagen, Concrete Blonde, Cat Power, The Gossip, Peaches, Amy Ray of the Indigo Girls and Margaret Cho.

The albums discography of Wanda Jackson, an American recording artist, consists of forty-five studio albums, one international studio album, seven tribute and cover albums, four live albums, twenty-one compilation albums, and two box sets.  In 1954 at age sixteen, Jackson signed with Decca Records as a country music artist.  The label did not issue a record until the 1962 compilation "Lovin' Country Style", six years after Jackson left Decca.  She signed with Capitol Records in 1956, and her self-titled debut studio album was released three years later.  Although Jackson had recently been identifying herself as a rock-and-roll performer, the album consisted of country music recordings.  However, it did contain Jackson's future rock-and-roll hit "Let's Have a Party", which was a hit in 1960, reaching the Top 40 on the Billboard Pop chart.  The success of her rock-and-roll recordings led to the release of two more rock-and-roll studio LPs: "Rockin' with Wanda" (1960) and "There's a Party Goin' On" (1961).  Additionally, Capitol issued two "split" studio albums ("Right or Wrong" and "Two Sides of Wanda") which contained rock and roll on one side and country music on the other.
