Samba-Rock, previously to make a song. But who can sing that ?
I first found the idea for intro with the basic program of Stratocaster on my old YAM DX7(1986). Left part of keys givin' a slap bass effect, i could play realtime both hands part following and opening for a suite, more drums & percs...on my keys of course! A last, this is a "Samba Bordelaise", Lol !!!!
Try to do it! Does Carnaval opens your imagination?
