Slap sounds are played similarly to a tone. Put your hand on the edge of the drum, but instead of playing with a flat hand, you curve your fingers lightly. The contact area is limited to the edge of the palm and the fingertips. The other difference is that your hands rebound immediately after a strike, so the contact time with the skin is as short as possible. Slap tones produce more of a ‘crack’ and a bright sound, but you’ll also notice a little bass resonance. Your hand should bounce off the drumhead so that the fingertip pads flick quite sharply on and off the surface with a slap. The pocket of space under the palm gives it a hollow sound.
Kakashi is another example of a great record that went into obscurity after its first pressing only to be dug out and rereleased by Better Days and Jet Set Records. Shimizu, a saxophonist and composer, worked with all kinds of musicians and collaborators, including Sakamoto and even artist Nam-June Paik. This record is deeply hypnotic and visits all kinds of soundscapes throughout, always with the saxophone placed at the center of attention.
