It's been a fair old while in the making – the first single, 'Wax', was released back in the summer of 2011 – but at last we have the first full-length from London indie-pop trio Theme Park. They built a buzz throughout 2012 with a dusting of singles and tours, including a support stint with Bloc Party on their UK comeback tour, along the way amassing a sizeable following. Most of the singles have found a home on the eponymous debut, with the exceptions of 'Milk', a long-standing fan favourite, and 'A Mountain We Love'. Theme Park have gone from strength to strength with each subsequent EP or single, winning over more hearts with their lucid, funk-tinged slivers of indie-dance every time they drop something new.

Album opener 'Big Dream' opens with melancholy tambourines and tight congas. It shuffles along, blending calypso rhythms, dominant bass guitar and the sombre vocals from Miles Haughton: "This time at night, our love is gone." Despite the bouncy facade, it's actually rather depressing, and much more pensive that previously released cuts have been. Recent single 'Tonight', produced by Friendly Fires' wiggly-pelvised singer Ed MacFarlane, is a candy-coated ode to an excitement for the now, a lust for the present. It's geared up to be a party staple, with lyrics about getting high and casual encounters aimed to be sung at painful volumes on Easyjet flights to Shagaluf.

As it is, the record is incredibly light. It's almost puffed up with the glee that warmer months inevitably bring, laced with glistening tropical beats and funky bass. Friendly Fires are an obvious, superficial comparison, however Theme Park are floatier, somewhat more psychedelic, but on the whole far less dark or overtly sexual. It's like the Weightwatchers version of MacFarlane et al. But then it's supposed to be a bit different – the music is a bit out of place in clubs, as it's too clean-cut, but for beach parties or sunny gatherings, it's a perfect soundtrack. It's made for the outdoors, with the breeze between your toes and the sand in your hair. Friendly Fires made a killing owning the niche of discotronica, but Theme Park have strived to own something with more freedom, less confined to the glitterati and autumn-dappled strobes of nightclub life, and with a stronger desire to hone a sound dedicated to summer holidays.

Big hit (well, sort of) 'Jamaica' is cowbelled up to the nines. There's a spout of jangly muted guitars, 80s new-wave keys and steel-pan synths – as the track wears on, in all it's viral catchiness, you get the sense that this is the 21st century 'Club Tropicana', which thankfully turns out a billion times better than you'd think. 'Los Chikas' is a semi-acoustic effort replete with 'oohs' about pretty girls and Haughton's penchant for register flipping. He alters between falsetto and booming baritone more than Kele Okereke would ever dare to. 'Wax' is a lolloping bass-driven charmer, with twinkling guitars and clicky drums. It's effortlessly optimistic, and a double measure of lethargy transforms standard indie-pop fare into blossoming Sunday morning motivator – radio friendly and designed to make you smile.

Theme Park showcase a tranquil sound full of grin-inducing hooks and providing ample opportunities to boogie. They're bound to be a regular fixture at festivals come summer, and for good reason – the sounds they make and a festival atmosphere sync up flawlessly. The only major drawback for the LP is the timing of the release: May or June would've been far more apt, and surely the band would see much more exposure during the time of year they'll be most relevant. It's unlikely they'll fade away any time soon, though, and plenty of youthful drunkards will be heard shouting the wrong words to 'Tonight' or 'Jamaica'.
