Picture this: It’s just after midnight, there’s a problem set due in eight hours that you haven’t started yet, and no study music seems to be working. Lyrics are distracting, but most instrumental music just doesn’t have the right tempo, or it all starts to sound the same. Orchestral music, movie soundtracks, and lo–fi hip hop were all meant as background music, but they get boring after a while. What you need is a driving beat and a grooving guitar hook to keep on task. Enter instrumental metal, the perfect study soundtrack, which manages to keep things loud, fast, and interesting without the distraction of vocals.

Instrumental metal and post–hardcore are exactly what they sound like: They feature loud and highly technical guitar work with a focus on complicated riffs, and a driving beat from the bass and drums. The genre operates at a faster beats per minute than most instrumental “study music,” and the lack of vocals allows the musical talents of metal guitar players to truly shine. 

Most instrumental metal tracks fall into one of two categories. First, there is progressive metal, a broad genre closely related to the vaguely defined post–hardcore. Broadly, it encompasses all metal with experimental elements, such as uncommon time signatures, syncopation, and unusual chord progressions. Within prog metal is a subgenre known as “djent,” named for the signature guitar sound: high gain, low pitch, distorted and palm–muted. The genre was pioneered by Meshuggah and Periphery, and bands within are noted for their use of guitars with more than six strings and for the technical prowess of their performers.

One of the seminal instrumental djent bands of the modern era is Animals as Leaders, a three–piece group that sounds little like its parent genre. Founded by guitarist Tosin Abasi in 2007 after the breakup of his old band, Reflux, the trio gained attention with a 2010 appearance on the Summer Slaughter Tour, alongside more popular acts like Decapitated and The Faceless. Animals as Leaders often takes a lighter approach to their riffs than those bands, pulling from jazz and electronica influences, among others. “The Brain Dance,” on 2016’s The Madness of Many, begins with an extended acoustic section that echoes Spanish guitar and American folk alike.

The other common name in the scene would be Polyphia, a mostly instrumental band based in Dallas, Texas. Like Animals as Leaders, they practice frequent genre experimentation: In a 2017 interview with Guitarworld, guitarist Tim Henson said, “We’re kinda closer to the whole pop side of things than metal.” Although they have gained popularity by touring with such major acts as Periphery, Between the Buried and Me, and August Burns Red, they cater to a smaller scene than those progressive metal giants. It comes as little surprise that their number one song on Spotify is “So Strange,” with a rare vocal line provided by singer–songwriter Cuco.

For a solid example of “standard” instrumental djent, one has to look no further than Their Dogs Were Astronauts, an Austrian duo formed by brothers Denis and Leonard Roth in 2014. Both brothers play guitar, and utilize backing tracks for other instruments when in concert. The sound is heavier than acts like Animals as Leaders or Polyphia, with a tremendous focus on the brothers’ guitar skills, and songs like “Low Life” would feel right at home in the soundtrack to a sci–fi action scene.

For those who want a choice between listening, there are the Dance Gavin Dance instrumental albums. Beginning this year, the post–hardcore band has begun releasing their old albums sans vocals, beginning with most recent release Artificial Selection and working backwards, putting out a new–old album every month. Because vocal lines were originally present, some selections sound empty, like Artificial Selection’s “Count Bassy,” while others, like Mothership’s “Chucky vs. the Giant Tortoise,” allow the aggressively talented instrumentalists to shine.

Instrumental progressive metal and djent have gotten short shrift, mostly from metal fans who prefer vocal lines, but bands like Animals as Leaders, Polyphia, and Their Dogs Were Astronauts have something to offer for everyone. For band members, particularly guitarists, it gives them a chance to show off their technical chops in extended form, outside a solo, and not hidden behind screams and growls. For the burgeoning guitarist, an interesting riff gives them something fun and challenging to practice. And for the student, these bands walk the line of being interesting to keep people awake and engaged in their essays and problem sets without distracting them into a sing–along.
