Falcon77 has 1 HEISA concert.

Jacques Nomdefamille (vocals, bass, keyboards), Koen Castermans (guitar) and Jonathan Frederix (drums) forge songs that sometimes surprise and enchant, then chastise again. Indie, yes, but nothing like the kind that you know. HEISA loves rhythms, atmospheres and keyboards, and breaking the patiently built up tension with painful guitars and waves of distortion at random moments. The vocals do not attract all the attention, but are an additional instrument.
