Input: Question: When was the artist born who made famous gated reverb? Passage:The group spent a year recording their first album, Days Are Gone, in sessions between live shows. The group experimented with drum machines and the music program GarageBand, adding hip hop and R&B influences to their existing sound. Polydor recommended producers Ariel Rechtshaid and James Ford to help with the album, who suggested further use of synthesizers, bringing the album closer to a straightforward pop style. Several of the drum tracks were recorded with gated reverb, made famous by Phil Collins. In June 2013, the group performed at Glastonbury Festival, and in addition to their own set, the band appeared with Primal Scream performing background vocals on "It's Alright, It's OK", "Rocks" and "Come Together". The band later returned for a repeat performance at Glastonbury in 2014. After their set, Este nearly had a diabetic seizure. She has Type 1 diabetes and was diagnosed with it in 2000.
