The Metal Box is a weekly web series posted each Friday where we discuss all things hard rock and heavy metal: news, videos, interviews, live concerts and more.

This week, we talk about Def Leppard cancelling their Winter 2016 tour dates due to singer Joe Elliot's vocal issues.

Def Leppard have sold over 100 million records worldwide. They continue to record, and remain a popular touring act. The band achieved the most commercial success throughout the 1980’s and early 1990’s. Initial success came with the 1981 album “High and Dry”, but it was 1983’s “Pyromania” that would become their breakthrough album, getting certified Diamond in the U.S. for 10 million copies sold and the mega hit “Photograph”. The band reached even greater success with the album “Hysteria” in 1987 with 12 million copies sold in the U.S. and over 25 million sold worldwide. The album “Adrenalize” also topped the charts in 1992. The band released their 11th studio album “Def Leppard” in Oct. 2015 and it cracked the top 10 of the Billboard 200 in the U.S.
