Similar experience seeing Ghost in de Vooruit in Ghent. Must've been 2016, back when they were called Ghost BC. Don't really follow them much anymore, but that venue was on fire.
Edit - Also amazing:
- Florence and the machine: amazing voice
- Ocean Wisdom: whole club bouncing up and down
- Macklemore: creates a rarely seen vibe with everyone
- Cypress Hill: such legends even after all these years
- Hooverphonic: insane voice and they are sometimes guided by an orchestra, so much power
- Parov Stelar: with an orchestra as well and my god it's really something to experience live
A lot of artists sound way different live, I've been disappointed as well but these definitely stand out.
Awesome you got to see them as well! They got big really fast, I saw them a year later at Alcatraz festival and that was at least 20x bigger and they were headlining IIRC. At that concert they had a canon shooting 666$ bills, I took some snaps for you. Tucked away between my record Ceremony and Devotion, the full live set just as I remember it but recorded in San Francisco.
