Same, I looked at the thumbnail and that fifth string got me to play the video immediately. I've never seen him playing a five-string bass. It's pretty cool that he's still experimenting.
Enjoying the comments, however; Victor did admit to Marcus Miller on a zoom interview that he has a certain condition with his fingers. In this video, notice how he handles his left hand and how he cuffs his index finger. Above all, he is a well accomplished Master of the Bass and will always be two or more steps ahead while performing! I remember as a Novice having hand cramps and finger stiffness at the beginning of a performance. Everyone knows that it is vital to warm up and hydrate properly before any performance, session or practice.
Mi recomendación a los bajistas. Aprendan a tocar mas instrumentos, asi no piensan que el slap y la escala disminuida es o mejor del mundo. Eso le gusta solo a los bajistas y no le impresiona a nadie.
There are not many musicians as good on 1 instrument as Victor is on his bass. So, depending on what level one is seeking to attain, a 2nd instrument is not good to learn. Instead, focus & mastery of 1 instrument is a better idea
