Cyberpunk 2077's side job "Second Conflict" allows players to choose between Johnny Silverhand's band members Denny and Henry.
Second Conflict only becomes available after the player has explored and completed a few side quests with Johnny. The plot of this job involves his old band and some of the band members, so it only follows that he and V should be on some kind of familiar terms. The choice between Denny and Henry comes at the very end of the quest, which hopefully gives players some time to weigh their decision.

Cyberpunk 2077: Second Conflict Denny or Henry Choice
For the sake of time: there is no long term consequence for this choice.
Don't worry. We don't begrudge players for checking—not after the impact the rest of this questline has. Better safe than sorry, right? Below, we've given the most spoiler-less explanation we can muster behind the decision.
Essentially, the quest ends with Nancy safe at Denny's mansion in North Oak. V should head to the back of the estate and find Henry and Denny at odds with each other, refusing to play the concert together. The choice of who gets to go up on stage now falls into V's hands.
Players are encouraged to pick whoever they like the best. This only affects who appears and plays the show with V and the dialogue options associated with the event. Otherwise, there is no true lasting outcome—at least, not with this.
