A preview of Soundgarden's upcoming appearance on the PBS concert program Live From The Artist's Den has been posted online, according to Blabbermouth. A crew from the Emmy-nominated series filmed the quartet's February 17th concert at the Wiltern Theater in Los Angeles, the last gig of a three-night stand there, and will air the episode sometime later this year. The set that night featured 28 songs from all eras of the band's career, including early rarities, hit singles, fan favorites and material from King Animal, the grunge legends' first set of new songs in 16 years.

On April 20th, Record Store Day, Soundgarden will release a limited edition vinyl collection of demos for King Animal. The six-song package will be pressed on 10-inch pink vinyl and will also include a free digital download card.

The demos were recorded by both singer Chris Cornell and the entire band at studios in Los Angeles and Seattle.
