Very good video Thanks for posting.
Backing tracks or an Arranger are necessary for certain situations due to economics. Tomorrow I'm doing a duo gig with my BK9 and a sax player. And not for a lot of money but hopefully will lead to other jobs. The people want all kinds of dance music. Did the same job a month ago alone and made more money but I just want to try something new.
Without the Arranger how do I do that ? I'm playing the keyboard parts and singing and the sax is adding the icing. Am I cheating ?
