“Two Sunsets” is a collaboration between Tokyo’s Tenniscoats and seminal Scottish guitar-pop act Pastels. Recorded over a few years in Glasgow during time off from Tenniscoats’ European tours, the album joins the growing list of joint projects by the Japanese avant-pop duo. Whatever Pastels have been up to for the past decade - and that includes running a record label, and soundtrack work for film and theatre - they haven't been recording albums: this is the closest they've come to such a thing since 1997's Illuminations. The two bands inhabit such similar musical worlds - dreamy places where vocals are wispy, melodies gossamer and the word twee never far away - that their alliance makes sense. But the bands' unselfconscious appreciation of each other brings something more: a buoyant confidence that infuses every subtly orchestrated note. You hear it best in Vivid Youth and Mou Mou Rainbow, both songs as insubstantial yet romantically affecting as a soft summer breeze.
