Rock fans have a nice surprise coming to them if they check out the soundtrack to the highly-anticipated Marvel Comics blockbuster The Avengers, opening this week: "Live to Rise," the first all-new single from grunge pioneers Soundgarden since their 2010 reunion. It's a promising sign of life from the group, who are slated to release their latest full-length LP later this year.

To commemorate that flurry of activity, Universal Music Group is releasing in Europe a special box set of the group's A&M catalogue. Classic Album Selection will feature, in one set, the band's four studio albums for A&M recorded between 1989 and 1996 (Louder Than Love, Badmotorfinger, Superunknown and Down on the Upside) as well as Live on I-5, a 2011 collection of live performances from the group's last tour in 1996.

There doesn't seem to be any differences in mastering, and there are no bonus tracks included, but all albums are being housed in mini-LP sleeve replicas. So if you're a collector or are curious to deepen your knowledge past 2010's Telephantasm compilation, now might be your best chance. The box is out on May 21 in the U.K. and a week later in the States.
