There’s something very cheering about the quietly blossoming career of Cate Le Bon. Each of the Welsh songwriter’s last three albums have won new fans for her idiosyncratic guitar pop, and she is now a cherished indie institution. Her fourth has the usual abundance of ideas; its scratchy guitars, free-associating lyrics, plinking keyboards are crammed into three-minute songs until they strain at the sides. You might feel less tolerant of its jarring arrangements and musical whimsy were it not for the moments of melodic sweetness that surface, as on the wistful Love Is Not Love. But this is still a wonderfully disordered junkshop of a record and a pleasure to explore.
