In Rai's words:  

'One distinguishing feature of 'Rikyrah' is that it's based around a particular upright piano housed in Perth, Australia, at Greg Nosow's studio. Greg also engineered this EP. After a few bars of playing, Ben (Vanderwal) and I discovered that the instrument is absolutely brimming with character, but it's also tuned 'in between the cracks.' What I mean, is that although it's in tune relatively with itself, overall its tuning is lower than standard A440 concert pitch. So, on 'Rikyrah,' we tuned the bass instruments and all other harmonic and melodic instruments by ear to this actual piano. (For those that could be wondering, the piano was NOT tuned deliberately to the popular 432hz, it's just old and has its own thing going on.) This unique pitch and tone served as an 'anchor' for the recording sessions, influenced much of the creative dynamic for our performances, and even the song choices are a follow on from this. The cover image of the EP features a fantastic painting by Anaïs Barajas, an artist who is based in Los Angeles.'
