Schweet Entertainment, the production company of Jack Osbourne, son of BLACK SABBATH singer Ozzy Osbourne, has produced a three-and-a-half-minute video, "In Studio With Black Sabbath: Ozzy, Geezer & Tony… Together Again", about the making of the band's new album, "13" — the first in 35 years to feature Ozzy, bassist Geezer Butler and guitarist Tony Iommi. Check it out below.Asked by Jack if there was any sort of trepidation about recording a new album, Ozzy replied in a Fuse video report: "The pressure was on us, because it had been so long since we'd worked together. It's, like, now or never. This album, for me, was probably the most important of my career." Iommi stated about the writing process for the LP: "I had a bunch of riffs on CDs and played it to everybody, and then everybody decided, 'We like this one' or 'We don't like that,' and the ones we liked, we started work on them, built them up." Jack also asked SABBATH if they had any apprehensions about working with legendary producer Rick Rubin, who is notorious for being very "in and out" of the studio while records are being made. "It was funny at first, because coming to rehearsals, when we were actually writing the songs, he'd come down for like, five or ten minutes and then go," Iommi said. "Then he'd go, 'Call me when you've got another one.' So it was really strange. We'd never worked with anybody like that before." An invite-only listening party for "13" was held on Wednesday (April 10) at The Montalban in Los Angeles, California. Ozzy, Tony and Geezer surprised a crowd of fans and journalists by showing up unannounced at the end of the event. According to The Pulse Of Radio, the three bandmembers were greeted with cheers and thanked the audience for listening to the eight tracks aired at the party, which was introduced earlier in the evening by Jack. Loudwire noted the "bluesy," groove-oriented and heavy feel of the songs, saying, "Upon first listen, it's clear that BLACK SABBATH's '13' will be a standout metal album of 2013. Fans will hear a lot of what has made the band legends in the first place while experiencing the freshness of some new music." "13" is due out June 11 on Vertigo/Republic. This marks BLACK SABBATH's return to Vertigo, their original label, and the group's first studio album together since 1978's "Never Say Die!" They have sold more than 70 million albums together. Ozzy told an Australian radio station that "13" is "mind-blowing," adding, "It's better than my wildest dreams; it's so good." The drum tracks on the album were laid down by RAGE AGAINST THE MACHINE sticksman Brad Wilk following original drummer Bill Ward's decision to bow out of the reunion. BLACK SABBATH will make a rare television appearance when the band performs a new song on the season finale of "CSI: Crime Scene Investigation". The episode is set to air on Wednesday, May 15 at 10:00 p.m. ET on CBS-TV. The band will world premiere a song called "End Of The Beginning" from "13". The episode's plot follows the "CSI" team as they investigate a series of murder that resemble the sins in "Dante's Inferno", with the trail leading the detectives played by Ted Danson and Marc Vann to attend a SABBATH concert. Jack found fame through his family's MTV reality show "The Osbournes" and has since appeared in several other TV programs. In 2011 he produced a documentary about his father called "God Bless Ozzy Osbourne" which, according to The Telegraph, contained admissions from the singer's five children that Ozzy was not a good father in their younger years, and that their abiding memories were of him hopelessly intoxicated, or, more usually, absent altogether.
