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 #52 in Billboard.

Recorded during the Long John Silver tour, Thirty Seconds Over Winterland was the band's second live album, after Bless Its Pointed Little Head. The complete final concert of this tour may be heard on the Last Flight CD, released in 2007.

Flying Toasters lawsuit
In 1989, software company Berkeley Systems released its immensely popular After Dark screensaver. The best-known of the various screensaver options was Flying Toasters. Jefferson Airplane sued Berkeley Systems in 1994, claiming that the toasters were a copy of the winged toasters featured on the Thirty Seconds album cover.  The band's case was lost because Berkeley claimed no prior knowledge of the artwork, and the judge noted the band had failed to trademark the cover art.(Wikipedia)
