For me it’s Glass Animals. When I first listened to Heat Waves and other songs on Spotify they never struck me as masterpieces, but holy shit are they a VIBE when performed live… I was jumping like a child in their concert!
Isabel Larosa was also a pleasant surprise. I only knew her songs as those overdone in reels but damn is that girl (and her brother) born for the stage! She has insane energy and holds her audience even without a supporting live band.
Caroline Rose was absolutely stellar live. I don’t normally like that level of produced pop.
Holy Wave went from background muzak on recordings to euphoric vibes live.
