Heavy music presenter Christina Rowatt of Soundwave TV conducted an interview with vocalist Chuck Billy and guitarist Alex Skolnick of San Francisco Bay Area metallers TESTAMENT on Sunday, February 23 at the Sydney stop of this year's Soundwave festival in Australia. You can now watch the chat below.TESTAMENT's current tour of Australia is the band's first with returning bassist Steve DiGiorgio (SADUS, DEATH, ICED EARTH). TESTAMENT last month announced the departure of bassist Greg Christian. DiGiorgio rejoined TESTAMENT as Christian's replacement. Steve was previously a member of TESTAMENT on "The Gathering" (1999) and "First Strike Still Deadly" (2001) albums. Christian was forced to leave the band's North American tour with LAMB OF GOD and KILLSWITCH ENGAGE in November 2013 for "personal reasons." Filling in for him was EXODUS bassist Jack Gibson. "Dark Roots Of Thrash", a DVD/2CD release documenting TESTAMENT's sold-out headlining performance at the Paramount in Huntington, New York this past February, was made available on October 18, 2013 (Europe) and October 29, 2013 (North America) via Nuclear Blast Records. "Dark Roots Of Thrash" was produced by Get Hammered Productions, directed by Tommy Jones (DEATH ANGEL, KATAKLYSM, SOILWORK) and mixed by Juan Urteaga (VILE, EXODUS, SADUS, MACHINE HEAD). It captures a total of 19 live tracks with countless cams onstage and high above the audience, plus a special moshpit cam that makes you feel like you're a part of the show.
