How to play "Descending Slurs" on guitar

In general, we can think of descending slurs as a left hand rest stroke through the string. However, we don’t stay resting on the next string, we just touch it and go. It’s a sort-of snapping motion. If you’re an electric guitar player, this will likely be a fresh concept for you. With electric guitar, sustain is so long that we don’t often have to snap off the string like we do on classical. The snapping motion is essential for a long sustain and an equal quality sound compared to the articulation.
