squared-off rhythm

[Helga Tarasova]

Помогите, пожалуйста, разобраться, что за ритм такой?
The first seeds of heavy metal were sown in the British blues movement of the '60s, specifically among bands who found it hard to adjust to the natural swing of American blues. The rhythms became more squared-off, and the amplified electric instruments became more important, especially with the innovations of artists like the Kinks, the Who, Jimi Hendrix, Cream, and the Jeff Beck Group.
Рубленый?
