Adam "Nergal" Darski of Polish extreme metallers BEHEMOTH has worked with ESP to develop his first-ever signature guitar. "V" shaped HEX-7 signature model will be available in LTD version, with pickups, hardware and design according to Nergal's specs.Comments Nergal: "When ESP approached me about building my signature model, I was stoked! I've always been a fan of their instruments and I'm very grateful for giving me an opportunity to envision my idea of what a perfect seven-string guitar for extreme metal should look like! I already can't wait to test this beast on our upcoming summer tour with SLAYER and MARILYN MANSON!" BEHEMOTH has tapped Colin Richardson (MACHINE HEAD, SLIPKNOT, NAPALM DEATH, CARCASS) to mix the band's as-yet-untitled album, due out late summer via Metal Blade (USA) and Nuclear Blast (Europe). The CD is now being recorded in Radio Gdansk in Poland with BEHEMOTH, Daniel Bergstrand, and Woytek and Slawek Wieslawscy as producers. BEHEMOTH's Orion, Seth and Nergal will take part in a signing session at the ESP booth on April 4 at the Musikmesse Frankfurt 2009 fair in Frankfurt, Germany. The signing will take place at 3:15 p.m. "Ezkaton", the latest EP from BEHEMOTH, sold around 1,600 copies in the United States in its first week of release, according to Nielsen SoundScan. The CD debuted at No. 26 on the Top New Artist Albums (Heatseekers) chart, which lists the best-selling albums by new and developing artists, defined as those who have never appeared in the Top 100 of The Billboard 200.
