Brighton rewards people who log the room
Patterns, Chalk, Concorde 2, and the Dome draw different crowds on the same weekend. A gig guide that says “Brighton live music” without the venue is hard to use later. Put the room on the gig card.
Londoners who travel down should still log Brighton as the city. The night is not a London show that happened to be on the coast.
Festival season is not the whole year
The Great Escape and on-season club bills are different kinds of entries. Log a festival as a festival. Log a Tuesday at Patterns as its own gig. Mixing them inflates your concert count and ruins the diary.
Radar already separates festival days from ordinary shows. Use that, then Find for whoever announces a Brighton date next.
Backfill from the trains you remember
If you remember the artist and that you came back late, you can usually find the date. Search the artist, filter toward Brighton, and save the night you attended.
Photos of the pier are not a venue. The venue name on the listing is.
