Space rock vocals

Hey y'all, I used to make hip-hop, but now I wanna experiment with another genre (punk rock/space rock) and I'm wondering how I should record the vocals. When I record rapping, I usually have a main take, and 2 back vocals take panned a bit to the left and right, where I double my rhymes basically. I wonder if that's what I should do with singing vocals as well. I wanna make music that sounds like this:

Thanks.
