Years & Years formed in 2010 with Olly joining the band as lead vocalist after guitarist Mikey heard him singing in the shower and reckoned he had "a good voice."

Olly's voice has been commented on by journalists for its unique tone with their music being described as "Nina Simone...crooning a melodic lullaby to the folktronic lovechild of Beach House and Terry Riley".

Their debut single proper 'Traps' achieved support from Radio 1 and Radio 6, as well as many online publications such as The Guardian and The Fader. 'Traps' also features on Kitsuné Maison's 15th Compilation.

The band released their second single 'Real' on Kitsuné and iTunes in February 2014 and the music video featured an appearance from Olly's 'Peter and Alice' co-star, Ben Whishaw. They are playing a few select shows in the UK as well as festival Les Inrocks in Paris, supporting Swim Deep.

Alexander is also set to appear in the film adaptation of Laura Wade's stage play Posh alongside British actors Sam Claflin, Max Irons and Douglas Booth.
