Creating duplicate fields in a node

I am creating a band site and want to be able to allow people to add their own review to the gigs that are listed in the "Gigs" node. In CCK I have created a node called "Gigs" with the info about the gig, date, venue, etc. and I could create a field called Review but that would be one field within that node.

I want to allow multiple reviews but am unsure how to go about it. I am thinking I might need a separate node called say gig review with relevant fields but I need to tie that node back to the actual gig by way of a link from the Gigs node.

I would appreciate if anyone has as a tutorial on setting this up or if you can point me in the right direction.

Thanks
