Hmm... I can't think of a lot of "Wall of Sound" related fics off the top of my head, so I went to the database.
Kaethel has a good fic about the walk home from the Kerth Awards in
Sweet Surrender .
Alisha Knight tells us what happens when Lois accompanies Clark to the Kerth Awards in her
Award-Winning Story .
VirginiaR continues the theme of post-Kerth-ceremony romance with her
First Kiss .
And Anonpip tells us Lois's thoughts as Clark wins his Kerth, in
Perceptions .
Ann McBride, in
A Triangle Built For Two makes Clark realize that he and Lois have to talk.
And the white rose in the episode plays an important role in Sue S.'s
Absolute Proof . This is the culmination of the "Proof" series and it really helps if you read the other ones first:
Proof ;
Proof And Consequences ;
Proof Or Dare ; and
Moment Of Proof . There is also an nfic goodie in this series,
The Naked Proof , which should not be missed.
As one might expect, writers tend to dismiss the A-plot and focus exclusively on the Lois/Clark relationship.
Another fic writer had a later villain steal Lenny Stoke's sound machine from the Museum of Crime and use it to interfere with Superman in what I think was a fic set post-Season-Four, but I forgot the fic and the author. Can anyone remember?
Addendum: Irene Dutch has a fun fic set immediately
after "Wall Of Sound". It's
The Spying Game and is well worth reading - it's fun!
