Three tracks of $60 Univox hollowbody in modified Fahey tuning (Bb F Bb F Bb C, compared to CGCGCE). Fingerpicking, with the barred sections being played as one finger moving a barre around. Somehow this came together quickly, over two short late-night sessions. There's the usual convolution reverb and compression/eq on the stereo out.

The title comes from the interesting galaxy cluster Abell 520,
