These gritty photographs show the real-life fight club where models, marines, and hipsters pummel each other during matches in New York's underground fighting circuit.

The photo series called 'Old One Two' by photographer Devin Yalkin captures the raw and unfiltered nature of the illegal fight clubs which take place in venues across New York city.

Reminiscent of the 1999 Hollywood movie called 'Fight Club' starring Brad Pitt and Edward Norton there is a no-holds bar attitude among strangers who step into the ring ready to draw blood on their opponent.

Aggression: Fighter Fischer unleashes several punches on his opponent as a crowd yells and shouts as both men fight it out

The fights take place in random venues dotted across New York City, where a baying crowd watches as fighters go head-to-head in the ring.

The violent event is completely unsanctioned but still draws in fighters who range from male models to millionaires.

Yalkin uses his lens to capture the striking, raw, enigmatic and intoxicating fights that are as far from mainstream boxing events as can be.

The images have a savage quality to them which convey just what it might be like to attend the sporadic fights thrown on Friday nights.

Yalkin told Featureshoot.com that he wanted to give the viewer a front row seat at the event, one which would pull you in and allow you to experience the loud, noisy and aggressive nature of the fight clubs.

He said: 'My relationship to my camera, my subjects, how in or out of focus the picture is as well as the framing, all depend on my levels of intimacy, fervency and comfort with the situation.'

Yalkin says he first heard about the event through friends.

He was eager to check it out and arrived at a giant building in Manhattan’s Lower East Side in 2010, where he was joined by a huge crowd who climbed a staircase and entered the fight room.

He told Time: 'The scene was rampant. The music was shaking the walls as if there was a subway going through the floor below us.'

He says he was 'drawn to the spectacle of the fights' which egged him on to capture it on film. He began shooting his series in November 2010.

He reveals that his adrenaline would pump every time he watched a fight, and this, he believes is why so many enjoy attending the events.

Yalkin, who lives in Brooklyn, New York, graduated from New York's School of Visual Arts in 2010.

He is a first generation Turkish-Armenian-American and uses photography as a vehicle to capture the grittiness of a host of events.

This series was also published in The New York Times in April 2012 as well as TIME Magazine's LightBox in 2011.
