They're taking a road trip from one home of Jazz to another; from Louisiana in the south to New York in the north.
Does that make more sense?
Both New York and Louisiana are considered to be places where Jazz is part of the music scene. They are going by road from one to the other.
A road trip means that they will be traveling either by bus or car or some other form of road transport. (I don't imagine it will be bicycle though)
