By continuously adding new dimensions of experimentation with harmonic voicing, odd meters and ambitious conceptual narratives, bands like Rush, Yes and Pink Floyd made sure that progressive rock steadily rose as a new and exciting alternative to the more mainstream-friendly rock format predominant during the 1970s. Suddenly, there was nothing odd about a ten-minute rock opus that progressed, moved and took on new shapes as it went. Very often in these compositions, keyboards played a central part.

This pack takes off in the wake of this era and gives you a broad palette of unconventional chord progressions, off-kilter harmonic ideas and inspirational melodic work. Music has no rules – and with a collection of playing variations that starts in 4/4 and ends up in 11/8, you’d better start experimenting!
