There is default it defined, you can use it to return matched elements:

var mydataGrouped = mydata.GroupBy("Shop", "it");  

To iterate through results you should additionally Select elements to name it and use dynamics:

var mydataGrouped = mydata.GroupBy("Shop", "it").Select("new (it.Key as Shop, it as Albums)");

foreach (dynamic group in mydataGrouped)
{
   foreach (dynamic album in group.Albums)
   {
      Console.WriteLine(album.Author);
   }
}
