Rhythm Machines 3 features the drum machines/drum computers released commercially for use in music recording between 1990-2020. The 1990s saw a noticeable decline in drum machines, as keyboard workstations and samplers negated the need for stand-alone drum machines.

By 2000, the high values of the classic 1980s units saw the emergence of several companies offering clones of these vintage units. Rhythm Machines - From Decline To Retro Designs contains information on over 80 drum machines, from Acidlab to Boss to Cheetah to Elektron to Jomox through to Zoom, packed into 140 colour pages.

A must-have follow-on book for the colour print Rhythm Machines-The Rise And Fall Of The Presets, which features the early dawn of rhythm units up to the emergence of the programmable drum machines, and Rhythm Machines 2 - The 1980s Drum Computers, which features over colour packed pages of information on all 1980s programmable drum machines, drum machine software for computers, sampling drum machines, a few preset pattern boxes, and even drum units manufactured in Eastern Europe. .
