NUSearch, Northwestern University Library's search tool, can be used to find books and other library resources. To search for books, it is best to click on the "Books, Images, & More" tab; otherwise, you are likely to be overwhelmed with articles.
Sample Searches:
"music festivals"
"music festivals" AND "vip tickets"
concerts AND luxury
"live music" AND economics
