Thirty Seconds Over Winterland is an album by the American psychedelic rock band Jefferson Airplane.

It was recorded live in August and September 1972, at the Auditorium Theatre in Chicago and the Winterland Ballroom in San Francisco.

It was released in April 1973; reflecting the band's declining commercial stature, it only peaked at No.

In 1989, software company Berkeley Systems released its immensely popular After Dark screensaver.

[6] The band's case was lost because Berkeley claimed no prior knowledge of the artwork, jacket cover art work had to be registered separately from the sound recording, and the judge noted the band had failed to trademark the cover art.
