I find this art form to be the most freeing for me. The use of free form brush strokes is appealing to me. A lot of emotion can be captured in this method. This technique can also bean extension of the artist sub conscious which for the most part can be eccentric to say the least but always liberating.
The artist that I admire in this genre are; Kadinsky, Pollock, Basquiat and Lewis.
I also like to draw freehand.
