The instrumentation of the whole album sounds a bit off key (that may just be me not being used to the Sharp X1). However, the tunes are still great and catchy and there's a lot of good stuff if you can just embrace the sound of the synth. From a modern standpoint, I'd give this an 8/10 just because the hardware limitations just do not sound as nice as later systems do. But, still a fairly strong album and the composer performed wonderfully.
