An excerpt of what he says about the song:
This song, recorded in September 2010, marks the point at which I began combining 60s and early 70s production styles with modern electronic production styles. This song was also the first time I successfully balanced pop music with abstract forms of music. This song showed me that the pop parts of myself and the more adventurous parts of myself could blend without one compromising the scope of the other.
