In the realm of popular music, most songs are fairly short and feature relatively standard song structures. These simple structures, combined with an infectious riff or a catchy vocal line are used to get stuck in your head. As you can imagine, not every musical act is aiming for such accessibility. Chicago, Illinois’ doom metal band Bongripper is a prime example of this, eschewing vocals entirely and plumbing the depths of a riff for upwards to 30 minutes in a single song. Despite this, their songs are surprisingly compelling, slowly evolving over their lengthy run times, layering new elements at a glacial pace. The band is a four piece, consisting of Ronald Petzke on Bass, Daniel O'Connor on Drums, and Nick Dellacroce and Dennis Pleckham on guitar. Their ridiculous band name came out of a joke about Sleep’s Dopesmoker neglecting to use all of the space on a compact disc (Dopesmoker is a single, 63 minute song about the Weedians traveling to Jerusalem with bongs strapped to their backs). They set out to write a song that used all 80 minutes of a compact disc’s run time, and recorded their first release, The Great Barrier Reefer in 2006.
