title: getting an empty array from a request to eventful api
body: <p>Im trying to use the eventful api to get information about only music events (concerts) between two dates. For example I want to get the below information about each concert from 20171012 to 20171013:</p>
  
  <pre><code>- city
  - performer
  - country
  - latitude
  - longitude
  - genre
  - title
  - image
  - StarTime
  </code></pre>
  
  <p>Im using a python example available online and change it to get the data above. But for now its not working Im just able to get this information:</p>
  
  <pre><code> {'latitude': '40.4', 
    'longitude': '-3.68333', 
    'start_time': '2017-10-12 20:00:00', 
    'city_name': 'Madrid', 'title': 'Kim Waters &amp; Maysa Smooth en Hot Jazz Festival'}
  </code></pre>
  
  <p>But the  performer, genre country and image url its not working. Do you know how to get that information? When I change the python example below to get this information it returns always a empty array.</p>
  
  <p>python example working: (However, without getting the performer, genre, country and image url, if I add theese elements to the event_features I get an empty array)</p>
