On January 23, 2010, Jay-Z released a track, "Stranded (Haiti Mon Amour)", with Rihanna, and U2's Bono and The Edge, as well as performing it at the Hope For Haiti Now telethon. In June 2010, Eminem and Jay-Z announced they would perform together in a pair of concerts in Detroit and New York. The event was dubbed The Home & Home Tour. The first two concerts rapidly sold out, prompting the scheduling of an additional show at each venue. Jay-Z was the supporting act for U2 on the Australian and New Zealand leg of their U2 360° Tour, beginning in Auckland, New Zealand, in November 2010, followed by Melbourne, Sydney, Brisbane and Perth in December. Jay-Z also appeared on stage during U2 performances of "Sunday Bloody Sunday", and in Auckland also on a five-track EP entitled Watch the Throne. Although, it was later revealed by West that the project had become a full-length LP. Recording sessions for the album took place at various recording locations and began in November 2010. The first single released for the project was "H•A•M". The track was co-produced by Lex Luger and West himself. The track ended up being on the deluxe edition of the album. The follow-up to that was the second single "Otis", which premiered on Funkmaster Flex's Hot 97 radio show, and was later released to the iTunes Store eleven days later. The song's existence, along with several other tracks from the album, was confirmed during a listening session hosted by Jay-Z. The album was first released on the iTunes Store, five days prior to it being released in physical format, a strategy Jay-Z later said was used to block an internet leak. It debuted at No. 1 on the iTunes Store in 23 countries. It also broke Coldplay's record for most albums sold in one week on the online retailer, selling 290,000 copies on iTunes alone. It held that record, until Lil Wayne's Tha Carter IV was released twenty-one days later, selling only 10,000 copies more. It debuted on the U.S. Billboard 200 chart at No. 1, selling 436,000 copies in its first week. The album received generally positive reviews. Jay-Z and West later gave a surprise performance of "Otis" at the 2011 MTV Video Music Awards. In April 2011, Jay-Z launched a blog-like, lifestyle website by the name of Life + Times. It covers everything from music, to fashion, to technology, to sports. The site is curated based on Jay-Z's interests, and he himself works with a small staff to produce every single piece of content.
On September 23, 2010, Q-Tip confirmed working on Jay-Z's follow-up album to The Blueprint 3, saying the album was to hit stores by spring 2011. In May 2012 it was reported that Jay-Z would work on new music with Roc Nation producer Jahlil Beats. Beats told XXL magazine: "Me and Jay-Z been going back and forth. He picked a couple of my joints that he's working on. I don't even wanna say too much about Jay, but we definitely working on some stuff. I haven't even sent him a bunch of beats. I sent him my favorite stuff. He hit me right back like, 'Yo, I'ma go in on this,' or, 'I like this.'" The album has been named one of the most anticipated albums of 2013 by Complex Magazine, MTV, and XXL. Production will come from Jahlil Beats, Kanye West, Rick Rubin, Swizz Beatz, Timbaland, and Pharrell Williams. Jay-Z also made an appearance on Justin Timberlake's comeback single "Suit & Tie" from his third studio album The 20/20 Experience, the song itself was produced by both Jay-Z and Timberlake's mutual friend, Timbaland. Timberlake and Jay-Z embarked on the co-headlining Legends of the Summer Stadium Tour. During the fifth game of the 2013 NBA Finals, Carter announced his twelfth studio album, Magna Carta Holy Grail, and was released on July 4, 2013. Not long after, Jay-Z confirmed that the hyphen in his stage name would be left out and officially stylized in all capital letters. Magna Carta Holy Grail debuted at number one on the Billboard 200 and sold 528,000 copies in its first week, which bypassed its predicted debut in the range of 350,000 to 400,000. In December 2013, it was announced that Jay-Z had received nine nominations at the 2014 Grammy Awards, more than any other artist. Jay-Z appeared on his wife Beyoncé's self-titled fifth studio album, Beyoncé, with a feature on the song "Drunk in Love". They performed this song together at the 56th Annual Grammy Awards opening. The song and its accompanying album would later win three Grammy Awards including Best R&B Performance at the 2015 ceremony.
