The duo, psych-pop artist Oliver Wilde and Lucky Shivers' Nicholas Stevenson, are following up the lead single "Overthrown" with "Martial Arts Washing Cars", which has some Malibu-shot visuals directed by Wilde's brother Lucas.

This new single features fellow Bristol act Nugget, and melts quaint vocal harmonies with summery strums and howling production - if they dialled up the twee a tad this'd be a shoo-in for the Best '70s Kids TV Show Theme award, but they haven't. As it is it's wondrously raw, with frayed edges that feel on the verge of unravelling and brilliantly brittle tones aplenty.

Penrose Winoa was recorded over five days in Oliver Wilde's living room with analogue equipment. It boasts 16 tracks (none over three minutes), with plenty of background noise (Sparklehorse the cat apparently makes a guest appearance) and lo-fi fuzz, and is inspired by "each other, Wikipedia holes, and a Dadaist game of consequence". Orchid Tapes' Warren Hildebrand (Alex G, Elvis Depressedly) is on mastering duties.

Oro Swimming Hour play Bristol's Thekla with Sweet Baboo on 17 June, the city's At The Well Launderette on 21 July for an album launch party (tickets come with a numbered risograph print designed by Stevenson), and on 27 August they hit The Louisiana for Hardly A Party with Beach Fossils, Girl Ray, and Ultimate Painting (plus others). The band are apparently welcoming requests to play "your living room, kitchen, or local launderette."
