The Dean MKH is an electric guitar made by the guitar company, Dean Guitars.
 It is a variation of the classic Dean ML, and this “newer” version was designed by Matt Heafy of the metal band, Trivium in 2008.
 Originally Matt Heafy first tried to create an original body style when he was approached by Dean Guitars, and he also attempted to make a modified version of the ML body style but he did not like what he came up with because he stated whatever he tried it just turned out to like something that has already been done before, so he picked this body design because he loves the ML body shape.
 And proof of this is that a lot of his guitars are the Dean ML body shape or altered versions of this guitar.
 For example, the Dean Razorback which he has in multiple colors like his white with gold trimmed USA Dean Razorback and a couple of Dimebag Darrell's signature models as well, like the USA Dean Dime Explosion.
The Sin and the Sentence is the upcoming eighth studio album by American heavy metal band Trivium.
 It is scheduled to be released on October 20, 2017.
 The album will be the first to feature fifth drummer Alex Bent (formerly of Battlecross and currently of Brain Drill and Dragonlord), who replaced drummer Paul Wandtke.
 With the release of the album's title-track, this album would also mark the return of frontman Matt Heafy's screaming vocals, which were completely absent from the band's previous album "Silence in the Snow" due to an injury which caused Heafy to blow out his voice.
Roadrunner United was a project organized by the heavy metal record label Roadrunner Records to celebrate its 25th anniversary.
 It culminated in an album released worldwide on October 11, 2005, entitled "The All-Star Sessions".
 Four "team captains" were chosen to lead 57 artists from 45 past and present Roadrunner bands, and produce and oversee the album's 18 tracks: then (now former) Slipknot drummer Joey Jordison, Trivium frontman and guitarist Matt Heafy, Fear Factory guitarist Dino Cazares, and Machine Head frontman and guitarist Robb Flynn.
 The unprecedented project was the brainchild of Roadrunner UK General Manager Mark Palmer and Roadrunner USA VP of A&R Monte Conner.
 The album project was coordinated by Lora Richardson and was mixed by Colin Richardson and Andy Sneap.
 "The All-Star Sessions" spawned one single and music video ("The End").
 The DVD included with the CD purchase is a documentary of the "Making Of" the songs.
 It features the sessions of the four team captains making their songs.

Trivium is an American heavy metal band from Orlando, Florida.
 Formed in 1999, the group originally featured bassist and vocalist Brad Lewter, guitarist Jarred Bonaparte and drummer Travis Smith, all of whom were students at Lake Brantley High School.
 Shortly after the band's formation, Matt Heafy was enlisted as lead guitarist by Lewter, after he saw him perform at a school talent show.
 Lewter later left the band due to differing musical tastes from the other three members, after which Heafy took over on vocals.
 Trivium subsequently became a four-piece with the addition of rhythm guitarist Brent Young, as Bonaparte moved over to the role of bassist.
 Bonaparte would also later leave the group after choosing to attend college, with Richie Brown taking over temporarily.
 After Brown's departure, Young took over on bass.
