Steve Albini was another important influence on the grunge sound. Albini prefers to be called a "recording engineer", because he believes that putting record producers in charge of recording sessions often destroys the band's real sound, while the role of the recording engineer is to capture the actual sound of the musicians, not to threaten the artists' control over their creative product. Albini's recordings have been analyzed by writers such as Michael Azerrad, who stated that Albini's "recordings were both very basic and very exacting: like Endino, Albini used few special effects; got an aggressive, often violent guitar sound; and made sure the rhythm section slammed as one."
