Avenged Sevenfold, Warner Bros., Keith Urban Avenged Sevenfold brought Elizondo in to produce their fifth album, Nightmare, in 2010. On choosing to work with Elizondo, guitarist Zacky Vengeance said: "Mike Elizondo loves Metallica, Megadeth and Iron Maiden, but he's also a musician and artist, and he's never worked on a rock album. So it seemed perfect, because we wanted to come up with something new and creative." Nightmare debuted at No. 1 on the Billboard album charts. In January 2011, recruited by Lenny Waronker and Rob Cavallo, Elizondo was named Sr. VP of A&R and Staff Producer at Warner Bros. Records. Mainly a creative role, he focused jointly on A&R and production, working primarily with Warner Bros. artists, including Gary Clark Jr, Mastodon, Kimbra, Jenny Lewis, The Regrettes, JR JR, Eli "Paperboy" Reed, Daye Jack, and Echosmith, the first band he signed. In addition, he produced Avenged Sevenfold's follow-up to Nightmare, Hail to the King, and played on and co-produced Gary Clark, Jr.'s Blak and Blu, and in 2012 reunited with Regina Spektor to produce her album, What We Saw from the Cheap Seats.In 2013, to "keep things fresh for himself and his fans," Keith Urban collaborated with Elizondo, who co-wrote and co-produced two tracks on his album, Fuse. A fan of Elizondo's work with Dre, in an interview with the Los Angeles Times Urban said: "He has a great rhythmic gift as a bass player, is an incredible drum programmer and multi-instrumentalist. My music is very, very rhythmic-based...I wanted to explore a much stronger presence of rhythmic elements in my music. It's something that's been there, but often has been pushed to the back." The album debuted at No. 1 in Australia and the US. Twenty One Pilots, Hamilton Mixtape, Live from Here In 2015, Elizondo was contacted by Lin-Manuel Miranda to develop The Hamilton Mixtape, which would be based on (but separate from) Hamilton. Using live cast recordings and a verse from Roots frontman Black Thought, Elizondo created a version of the musical's "My Shot" that became the first song on The Hamilton Mixtape, "setting the standard and attitude of the project." Elizondo also produced "Satisfied," by Sia (featuring Miguel and Queen Latifah) and Andra Day's cover of "Burn", giving it a "classic, old-school R&B vibe with hip-hop drums and overtones." Elizondo also produced four songs on Twenty One Pilots breakout album Blurryface in 2015. The second single
