That time when you're at a festival, local gig or watching a support band. Either way you've never heard of them, have absolutely no expectation and then.... wow.
For me, this was Adem supporting Hope of the States at Manchester Academy 3 about, well whenever that first HOTS album was- 2004? 2005?
First band on, and you could have heard a pin drop- he instantly stopped pint-holding chattering with a sound that was like somewhere between cracked-voice lullaby and the folk music they used to play on bagpuss. Never seen silence used so effectively as on opener Statued. Wonderful.
Bought the album at the gig, which is something I never do.
