#LSTMTNS Bloc Party: The Blue Mountains Party We Know Nothing About

Could this year's instalment be a nod to Paris and its cultural centre?

The #LSTMTNS Bloc Party is back for the fifth year, and like the four that came before, we know very little. 

These underground concerts are shrouded in mystery, and yet the $124.95 tickets are snapped up and sold out each year, with punters ready to be blindly led into what we can imagine is an experience not to be missed.

If you are someone uncharmed by the drama of a site-unseen concert, then the #LSTMTNS Bloc Party won’t be on your bucket list. There are no phones allowed, and the line-up and location are not revealed until three days before. 

There is something freeing about surrendering to an experience that you cannot control or even learn about until you are there… but boy, we would love some first-hand experiences.

The website is a greyscale page with dreamy pictures of mountains, untouched landscapes, and thunderstorms. The mystery of it all taunts the average punter, begging for more information. 

For a festival provider to withhold information from the public and be seemingly unbothered by the promotion of the event feels so unheard of in 2025, with most major festival organisers feeling the pinch and going full throttle on promotion.

Now, that’s not exactly true. The website does say the location is “bloc party is located in the Blue Mountains. Hidden venue directions will be emailed to all ticket holders after purchase”. There is a more cryptic message still, with the coordinates of “48° 51' 29.1348'' N, 2° 17' 40.8984'' E” halfway down the homepage, which appear to be the coordinates of Cathédrale Notre-Dame de Paris, considered to be the historic centre of the city. 

What does it all mean, you ask? Could this year's instalment be a nod to Paris and its cultural centre? Well, it might just be that you never get the full picture. 

The #LSTMTNS Bloc Party is shrouded in mystery, but #LSTMTNS as a destination is familiar to many in the know. The name 'LSTMTNS' is actually the Australian Bureau Of Meteorology (BoM) station code for Lake St Marys Mountains/Blue Mountains. This title has taken on a new meaning for those who live and love these mountains, and #LSTMTNS has become a movement in and of itself. 

‘Blue Mountains Explore’ started in 2016 as a group of adventure-loving locals sharing canyoning, climbing, bushwalking, and trail-running trips on Instagram

Their posts quickly built a large, engaged following. As they mapped new spots, they tagged them with #lostmtns, and the hashtag grew into its own identity—the group became known as the #lostmtns team. The team releases guidebooks often, averaging in about $70-$90, showcasing the best places to swim, camp and general tips for navigating the area.

How involved this group is with the Bloc Party concert is, you guessed it, a mystery. But we would wager that they have had a heavy hand in choosing the curated spot for the concert, as they know the land like no other. After all, wouldn’t you want an intermediate group of nature explorers choosing the destination for an outdoor music event?

Punters can have the chance to win a Golden Ticket to the Bloc Party by ordering one of the guidebooks with a ticket enclosed, which affords them and a friend free entry into the party.

These Golden Tickets are only eligible to be won during the pre-order stage of the guidebook release, and so punters should keep an eye out for this next year if they are feeling lucky. This exclusive chance and subtle push to order a guidebook is a marketing chef’s kiss, but why not?

It’s crazy to think that in the 2020s, there is a festival experience where there are no phones allowed and no way to really see what has gone down at the last four coveted events. In a time where most will capture a music set on film, snap a fit and put it all together in a curated photo dump, punters will have to forgo the social media humble brag. 

They do not have any evidence of this Blue Mountains experience, so we have to think that this would attract a unique and fun collection of individuals.

Research on Reddit and Instagram shows some whinging about the secrecy, but most of the engagement is excitement and desperation to get on those mountains. We will continue to keep our detective hat on and mine the mass of social content to find the hidden threads of this emerging musical event.
