Rush on Jammit
Rush have teamed up with Jammit, the number one app for you to learn your favourite songs, and have made available Rush’s classic songs 2112 and Limelight. Rush on Jammit gives you access to the original Rush multi-track masters, with instrument-specific versions available for drums, bass, guitar and vocals with the precise notation and tablature. In addition to being an exceptional learning tool, each Rush song can be analyzed by isolating the individual instruments from the rest of the mix, slowing down the speed (without changing the pitch) and looping difficult sections.
