There are several gift ideas that you could consider for your friend who loves rock concerts. Here are a few suggestions:
1. Concert tickets - This is an obvious choice, but a good one. Perhaps you could get tickets for a band that your friend has been dying to see but hasn't had the opportunity to yet.
2. Band merchandise - Most bands have merchandise for sale, including t-shirts, hats, posters, and more. You could get your friend a t-shirt from their favorite band that they could wear to their next concert.
3. Record player with vinyl records - Many rock bands release their music on vinyl, and listening to records can be a fun and rewarding experience. A turntable and some of your friend's favorite records would be a great gift.
4. Rock documentary or musical biography - There are many documentaries and biographies about rock bands and musicians that your friend may be interested in. You could get them a DVD or Blu-ray of one of these films or a book about their favorite band.
5. Portable phone charger - This may seem like an odd choice, but many concert-goers find that their phone batteries die quickly at shows. A portable phone charger will allow your friend to keep their phone charged so they can take pictures and videos, as well as keep in touch with you after the show.
