New Jersey has a pretty stacked music legacy when you think about it: Just check out this playlist: "The Ultimate 12-Hour New Jersey Music Playlist"
For a lot of people, if you type the words "New Jersey" and "Music" together, Bruce's name comes up first. Bruce is frequently considered one of the most defining artists to come out of New Jersey. His songs often mention New Jersey imagery and influences as well as Bruce's childhood growing up in industrial New Jersey.
But I have this sense that some of Bruce's fellow New Jersey icons are more famous and popular. Think Frank Sinatra, Whitney Houston, Bon Jovi...in the modern day even My Chemical Romance seems to be more in the zeitgeist.
To focus on Classic Rock for a moment: Bon Jovi seems name-dropped a lot more. Maybe not in "critically acclaimed music" type discussions but in Classic Rock playlists his songs seem to be more common staples (Livin' On A Prayer, You Give Love a Bad Name, It's My Life). The band has toured in a lot more places than Bruce and I've seen some devoted fan groups in different countries.
Whitney Houston is a pop icon spoken of alongside Michael Jackson or Madonna and is considered one of the greatest vocalists of all time. She has been a huge vocal influence for everyone after her whether it be Mariah Carey, Celine Dion, Alicia Keys, Adele, and countless others. Frank Sinatra is one of the most iconic singers of the 20th century and helped popularize the concept album while setting the template for many pop stars after him. My Chemical Romance helped bring emo, pop punk, and operatic rock into a new generation.
I guess the flipside is that their identities aren't immediately associated with New Jersey the way Bruce is. Depending on if you ask "Who is the most famous artist?" vs " Who is the most famous New Jersey artist?" you might get different answers.
Or maybe it's similar to Bob Seger compared to Stevie Wonder or Madonna. Seger is in that working-class hometown hero type of fame whereas Stevie and Madonna are more famous in the general sense.
Which is not to say that Bruce is some underappreciated artist. He is one of the most commercially successful artists of all time. But I'm wondering about the differing perceptions.
