Led by Amparo and Cristina Llanos, Dover has been one of the most important Spanish alternative rock bands of the nineties. Llanos' sisters were in charge of the vocals and guitars, as well as the composition and the control of the band. For this reason, Dover is one of the few examples of a gender mixed rock band in which the main roles are performed by women. This article reflects, taking as a common thread the review of the coverage of the group made by the music press between 1996 and 1998, on the biases and problems related to gender that Llanos' sisters had to face. Thus, issues such as the look for a "female" homosociality or strategies such as masculinization were crucial for the band to achieve legitimacy within nineties' Spanish rock scenes.
