Drum Line Dilemma

Hi everyone :)br
Does anyone know of any good tutorials explaining how to create a nice hard punching groove in your drum section?br
Im thinking of John Dahlbacks “Feel it” and Sebjak Schossows “Liceu”.br
These nice driving, compakt drum sections.br
Any good tutorials or any good tips and tricks?br
