Def Leppard have kicked off their 11-date, three-week residency at the Hard Rock Hotel and Casino in Las Vegas, posting a photo on Facebook from a Friday night appearance that included a complete reading of their smash 1987 album 'Hysteria.'

The band's first set focused on familiar hits like 'Foolin'' and 'Bringing on the Heartbreak,' as well as items from deeper in their catalog like 'Mirror, Mirror (Look Into My Eyes)' from 1981's 'High and Dry,' 'When Love & Hate Collide' from the 1995 hits package 'Vault,' and the title track from 1996's 'Slang,' among others.

They opened with 'Good Morning Freedom,' a rare B-side from the 1980 'Hello America' single. Def Leppard then performed 'Hysteria' in its entirety before returning for an encore of 'Rock of Ages' and 'Photograph.'

Afterward the band shared the photo above, posting, "Vegas has begun! The Joint is officially rockin!"

Though marked by tragedy after drummer Rick Allen lost his arm in a car accident during the recording sessions, 'Hysteria' would become the best-selling album of Def Leppard's storied career in arena rock. The project produced a string of hit singles, including 'Pour Some Sugar On Me,' 'Love Bites,' 'Armageddon It' and the title track.

Def Leppard's Las Vegas concert series, titled 'VIVA Hysteria!,' continues through April 13 at the Joint inside the Hard Rock Hotel.

Allen also debuted his own art exhibit, called 'Electric Hand: Rhythm + Change,' on Friday at Caesar's Palace in Vegas. He'll participate in a Q&A session at the Martin Lawrence Gallery there on April 4.
