17 tracks all featuring the mighty Mellotron. One track features the Chamberlin which was the Mellotron's precursor. To the uninitiated, the Mellotron was a primitive sampler. It was a keyboard that triggered pre-recorded tape loops. Some of the built-in sounds will surely ring a bell. 1:27 into the Radiohead track, the intro to the Genesis cut & :03 into the M. Ward song (that's the Chamberlin).
