ALAN ALLEN
Folk music icon, ornamental wood sculptor, Yogi and (barely) functioning alcoholic Alan Alen is nothing short of a Leg-End.
One half of the legendary Scottish folk duo Bridge & Allen, Alan rose to fame in the 70's, captivating audiences with his
heartfelt lyrics, soaring melodies, and undeniable stage presence. Together, he and his late partner Duncan Bridge defined
an era, inspiring generations of musicians who followed (er. Proclaimers & KT Tunstall). Their influence can still be felt
today, despite their untimely "retirement" in 1978, when they stepped away from the spotlight at the peak of their fame.
Now, after decades away, Alan Alen is back, bringing his incredible presence to Altitude*
This is a once-in-a-lifetime opportunity to witness a true legend in action. He'll be hosting an unmissable live podcast on the Penkenbahn Terrace on Tuesday, March 25th at 1 PM, joined by an incredible lineup of comedic guests. Completely unplanned and utterly unpredictable, this promises to be an unforgettable event.
We are beyond honoured to welcome true legend, Alan Allen, to the mountains this March. Failte!
JULES O'BRIAN
DIEDERIK ZUURMOND
Bringing his razor-sharp wit to the slopes for the first time, Diederik Zuurmond is a comedy talent you won’t want to miss. Diederik is a Dutch comedian with British roots, with humour that is uniquely absurd, dark and silly. One of the youngest comedians on the circuit but the ability and affability of an old pro.
With a knack for dissecting life's ridiculousness, his intelligent and thought-provoking humor will have you in stitches. Diederik’s approach to comedy is full of dry humour and clever insights that cut straight to the point faster than a skier cutting up a snowboarder on the slopes

SILENT DISCO
What’s the best way to keep warm on a mountain? No not thermals, it’s throwing some shapes with the Original Silent Disco crew!
Our mountain top silent discos are the ultimate fun that you can have against amazing mountain backdrops. Ski in and out, grab a drink, and join the party.
A silent disco has one noticeable difference from a normal party - there’s no music! That is until you put on your headphones to hear two first-class DJs playing an eclectic mix of tunes to have you stomping your feet, shaking and shimmying the day away. All you need to do is pick your channel and choose your side as your DJs battle it out over separate wireless channels.
