Who WAS that Parisian band?

So… I’m listening to RFI (Radio France Internationale) via the 'net tonight (4/25), and I heard this absolutely fantastic band playing in a Parisian club in the 11e, close to la Place de la Bastille. Unfortunately, I was busy reading the SDMB, and I didn’t focus enough on the broadcast to figure out what the band’s name was. I know the first song in their set was “Zion”… but no clue what their name was. Anyone out there familiar with this band?

Mass Hysteria?
