This has been remastered, straight from the original multi-tracks to CD. Sound quality is much improved from the original release on "Experimental Guitar". Anyone who's enjoyed these pieces from that- or even the small clip of "Discharge", on "Always"- is in for a treat, there is a huge quality difference.
But please take note: these are different mixes. In my opinion, they are superior. But as a listener, where other people's music is concerned, I know I've sometimes preferred the originals. The Experimental Guitar tape is no longer available, so the point is receding, daily, further into the distance.
