Joel Dias-Porter's Ideas of Improvisation interrogates how the I & I of the imaginary can appear perpendicular to the axis of the real. In addition to the expected body of words, he improvises on the idea of the lyric by marooning text to create ghost poems which float above the page and add a new haiku like dimension. Like the rook in brook, in Ideas of Improvisation we hear how Dias-Porter, a neurodiverse technician of the text, reformulates form to navigate the spectrum of possibility.
