I particularly liked the interplay between Petrucci's solid riff mid-section and Rudess ' Hammond organ improvisation in the gaps between the riffs.
Their sound is given an extra twist by having a Hammond organ in the set up.
A short instrumental with lilting lead guitar, gentle percussion, synths and Hammond organ.
The Hammond organ always does my head in and the guitar vocalist certainly knows what he ' s doing.
Originally released in 1972 on the album Machine Head, the four chord distorted guitar riff follows a basic blues scale and is eventually doubled by a heavily distorted Hammond organ playing the same line as the guitar.
