HALESTORM singer Lzzy Hale joined ADRENALINE MOB on stage last night (Friday, April 5) at Exit/Inn in Nashville, Tennessee to perform cover versions of "Come Undone" (DURAN DURAN) and "Barracuda" (HEART). Fan-filmed video footage of her appearance can be seen below.Hale recorded "Come Undone" with ADRENALINE MOB for the band's 2012 debut album, "Omertá". She previously stated about the collaboration: "After touring together [in 2010], I was approached by legendary drummer and equally as legendary great guy... Mike Portnoy. He was kind enough to ask me if I'd like to join them to remake the DURAN DURAN hit 'Come Undone'. Of course, I said yes, and ran to Mike Plotnikoff's home studio to do it! "Now, coming from someone who has lived and played with her own zany drummer all her life, I must say, it was next to orgasmic to sing against Mr. Portnoy's stylings. Truly an honor! "Thank you so much to all the guys in ADRENALINE MOB for including me on their record 'Omertà'. Go get it!" Asked how he got Lzzy to sing on "Come Undone", Portnoy told Audio Ink Radio: "She's somebody I'm friends with from touring together on Uproar [festival] a few years back. Lzzy and I became good friends, and when the idea for a female vocalist came up for 'Come Undone', I knew she would absolutely kill it! So, I her gave call, and without even hearing it, she was on board because she wanted to do something with me. Once she heard the tune, she was like, 'This is awesome. This is going to be great!'" He added: "Her voice just fits perfectly. The minute I heard tracks, the hair on the back on my neck stood up. It just gave me chills." In an interview with Guitar International, ADRENALINE MOB guitarist Mike Orlando stated about Hale: "Lzzy is a female Russell [Allen, SYMPHONY X and ADRENALINE MOB singer]; she is unbelievable. They have the same attack. There's nothing she can't do. Everything she does, she does with this fire." HALESTORM and ADRENALINE MOB will embark on a short tour of South America and Mexico in June. The bands will share the stage in Mexico City, Santiago, Buenos Aires and São Paulo.
