Aqualung first came to attention in 2002 when the debut single ‘Strange & Beautiful (I’ll Put A Spell On You)’ became a surprise UK Top 10 after being discovered via a Volkswagen Beetle advert. While that song created a magnetic allure, the strength and versatility of Hales’ songwriting further enamoured audiences. The debut self-titled Aqualung album reached Gold status in recognition of over 100,000 domestic sales, while the brighter symphonic scope of his second album, ‘Still Life’, led to another chart hit with ‘Brighter Than Sunshine’. By the time Aqualung’s third album, ‘Memory Man’ emerged, glowing comparisons had been made with everyone from Bacharach to Radiohead via The Beach Boys, while his music has featured in ‘Twilight’, ‘Gossip Girl’ and ‘Grey’s Anatomy’. At Aqualung’s recent ‘one night only UK tour’ (his first performance in the UK for 12 years at Bush Hall, London) Matt Hales let his devoted audience know just how clued up he is on streaming trends: As a songwriter and record producer, Hales has collaborated with Lianne La Havas, [6] Bat for Lashes, Tom Chaplin, Mika, Daniel Wilson, Kina Grannis, Andreya Triana, the Fray, Kwabs, Jason Mraz, Reignwolf, Sara Bareilles, [7] Jacob Banks, Paloma Faith, [8] Disclosure, Alex Clare, Mansionair, Mikky Ekko, For King & Country [9] and many others.Eliezer, Christie (16 November 2011).

None of this has been lost on Matt Hales. After all, not only does he make and release music as Aqualung, but he also writes and produces music for some very successful streaming artists, so he knows the score you might say. Yet on Aqualung’s latest album Dead Letters, he’s not bothered one bit about conforming to streaming conventions.

As those songs evolved into a catalogue of material, Hales reunited with some of the team behind the second Aqualung album, ‘Still Life’, for sessions at Real World near Bath, where that album was recorded. Those demos were finessed over the course of two years with some of his trusted collaborators: his brother Ben Hales, his wife Kim Oliver, and Matt Vincent-Brown, his bandmate in his pre- Aqualung projects The 45s and Ruth. It’s funny, but some musicians who have long careers are often apologetic about their most recent work. While this might have a touch more humility than the usual brazen fib “this is my best work ever”, they needn’t be. I wonder, has streaming got something to do with this? When an artist’s new work is so transparently ranked against their biggest hits, it must send a disconcerting message.Indeed, if ‘side one’ contains the big grand opener and ‘the (parallel universe) hits’ then ‘side two’ is the introspective half, full of personal stories, life sketches and dedications to family and loved ones. Each song is beautifully worked, with some rather wonderful chamber pop arrangements. On returning to England from the USA and making a new home in the South West, Hales was reacquainted with an old piano (which even came with vomit stains from prior family use). That piano adorns the inside cover sleeve of the album and proved to be the central tool in this record’s creation, with Hales composing sketch after sketch that eventually shaped themselves into the album's nine fabulous songs. ‘ Bad Dreams’, the album’s closer, is a masterpiece. It’s nearly 8 minutes long and not a second wasted. Finally, just before the needle gravitates towards the centre, Hales whispers ‘so’, just as the record started. Pearson, Beth (20 November 2002).
