Jannarelli is one of those guys that you can count on and recommend without fear to any producer.
He has the fundamental skills for those who need a bass player, whether for a recording or for a concert.
He´s got musicality, ear, equipment, musical knowledge, production knowledge. He´s responsible and committed to the task.
Carlos still has relationship skills that are indispensable, such as sympathy, being easy-going, respect and friendship.
I would recommend him without thinking twice.
