This is an album of classics (of classical music) played on the mellotron. If you have no idea what a mellotron is, well, let's just say that it's a precursor of the sampler but instead of playing wav files when a key is pressed, a tape rolls over a playback head (like a reel-to-reel tape deck or more recently a cassette player). As you can imagine, besides the fact that the needed tapes are a bit hard to come by these days (Even if you can find some, they have the tendency to desintegrate.), those things can be a little bit unpredictable and it takes dedication to produce one track, let alone a full album. I salute that dedication as it takes somebody quite special to undertake something like this.
I know this is not original work but it's always good to hear Bach and company, especially on a old school mellotron.
