i hear you riddim about maracatu, id go one step further and say its in Ketu Candomble drumming . A beat called OPANIJE is all up in new orleans beats and louis armstrong
and one great pattern in there is Bravum that has the swing pattern in it and the bell plays "jingle bell" like the figure in "jingle bell rock". i find if my bass drum goes for that jingle bell figure , it is simple and really gooses the swing.
Thanks. I have research to do.
