The band began touring in January 1994 in Oceania and Japan, areas where the record came out early and where the band had never toured before. This round of touring ended in February 1994. In March 1994 the band moved on to Europe. They began a theater tour of the United States, first with a stop on May 27, 1994 at the PNE Forum in Vancouver, with the opening acts Tad and Eleven. In late 1994, after touring in support of "Superunknown", doctors discovered that Cornell had severely strained his vocal cords, and Soundgarden canceled several shows to avoid causing any permanent damage. Cornell said, "I think we kinda overdid it! We were playing five or six nights a week and my voice pretty much took a beating. Towards the end of the American tour I felt like I could still kinda sing, but I wasn't really giving the band a fair shake. You don't buy a ticket to see some guy croak for two hours! That seemed like kind of a rip off." The band made up the dates later in 1995. "Superunknown" spawned the EP "Songs from the Superunknown" and the CD-ROM "Alive in the Superunknown", both released in 1995.
