Another development idea would be a 'Market Place' for collectors of 'Sun Records and Memoribilla'.
Sun Records was the founder of Rock and Roll and Elvis Presley's label so there is a huge 'Collectors' following of The Sun name.
Take a look at
http://www.sunrecords.com/
If you take a look at this Ebay link
http://search.ebay.com/sun-records_W0QQfromZR40 you will see there are 5,176 listings for Sun Records!!! All potential clients to join your 'Sun' market place and forum and if you search through artists like Elvis there are tons more listings.
Don't forget you could have links to Music Sites and Amazon (who sell tons of books on Rock'n'Roll History.
Develop this for a niche market of collectors - They are the type of traffic who spend money.
Another potential buyer could be The Sun newspaper in England, its the best selling paper and rather tacky with pinups and a good sports section, but they could use it to make a classified site for their readers.

Personally I like the first idea better. There is free forum software available and you can create the market within the forum.
Hope this helps, I don't think the domain has value without development but I always try to suggest positive angles.
Thanks for the previous Rep.
