( CNN ) -- The other day I saw a death metal band hanging out by their tour van in the parking lot behind a club . They were all dressed in black , and may or may not have been working on lyrics to a new song about fire and lamb meat . `` What rhymes with 'charred remains ? ' '' Now , I ca n't say for certain that they were actually death metal . But that 's what I 'm going with . Admittedly , I 'm not very up to date on the various sub-genres of growling into a microphone . Thus , when I do n't know any better , I find it 's always best to make assumptions . For instance , this morning I assumed I wore pants to work . The people in line at Starbucks assumed differently . But there they were , this supposed death metal band , all dressed in black , minding their own business on a lovely sunny afternoon in Atlanta . And I just stared at them with intrigue until I uttered the most old-man thing I 've ever uttered : . `` They 'd be so much happier if they just wore a little color . '' Which is a completely insane thing to think . They were probably loads of happy . And they seemed perfectly reasonable . In fact , maybe they were discussing how , if they pooled all their collective happiness and reason , they could open up a combination orphanage and puppy day care center called Unicorn Land . Shame on me for judging . Just because they wear all black and their music probably sounds like a horse choking on a watermelon does n't mean they 're angry people who eat children and worship Satan . Besides , that 's so Simon and Garfunkel . The point is , they have their thing . And I have mine . And just because I do n't understand or particularly enjoy death metal , does n't mean it 's not good music and , dare I say ... art . Because art is exactly what was being celebrated recently in London when a local death metal band called Unfathomable Ruination decided to lock themselves in an airtight , soundproof cube and play until they ran out of oxygen . The plan is to do it three nights a week , Wednesday through Friday , at 6 p.m. throughout the month of July . Or at least until they all forget the safe word and suffocate . `` I ... should 've ... gone ... to law school . '' The actual cube was designed by a Portuguese artist named JoÃ£o Onofre , and he calls it `` Box Sized Die . '' But what does it all mean ? Interestingly , the death metal art cube sits right outside the famous London office building known as `` The Gherken . '' That 's the one that looks like a giant suppository in the heart of the Insurance District . And the cube is supposed to represent the cold , dark working spaces within the surrounding office buildings . Onofre says , `` In this corporate architecture you do n't really see what 's going on inside . The same happens here in the work . You see it but , then again , you do n't see it when the performance starts . '' Look , I only barely get this . I now have five functioning brain cells , and I 'm not prepared to burn four of them trying to digest all the deep meaning from a weird public art display . So , I trust that whatever Onofre says makes sense . I 'm more interested in the music . Or , I suppose , the lack thereof . Being that the box is airtight and soundproof , all the music is completely inaudible to the public . They can only feel it . Which is actually kind of cool . Presumably , though , inside the box it sounds like your grandfather passing a kidney stone the size of a Chicken McNugget . But only for a short while . Ben Wright , the band 's lead vocalist , explained , `` We did 14 minutes the first time on the run through . And then we did 19 minutes today . '' So , it 's kind of like musical CrossFit , except this box is actually ... a box . And you do n't have to tell your Facebook friends about the sand bag you just lifted over your head . But , hopefully , as the month carries on , Unfathomable Ruination will keep playing for longer and longer . This , despite the fact that it does n't look very pleasurable . Really , they 'd be so much happier if they just wore a little color . Follow @ JarrettBellini on Twitter . See more content with questionable news value at CNN Comedy .
