please ask for a quote of your dream record ideas. below some things that may open your mind:
custom-shaped vinyl records
almost any custom shape that will not exceed 12" diameter that will have some space left for the recording
CNC engraving (etching)
etching is possible on non recordable parts like label space or corners (e.g. square records) and on unprinted or printed cover jackets as well
multi-hole records
records that have multi-center holes (each one for a song)
custom center label shapes
almost any shape
x-ray records
sound is cut on x-ray negatives (you must provide your own negatives). sound is usually mediocre and depends on x-ray negative brand/thickness. this is complicated stuff, please ask for details
