Hebridean polymath Colin MacIntyre refocusses his literary gifts on joyously tuneful guitar pop. After publishing his debut novel in 2012, the Scot has revived his one-man musical project. Only the whistles and parps on “Bones” echo the absorbing peculiarities of his earliest albums, but he’s still got warm intimacy and indelible hooks in spades, whether he’s making ragged indie-rock (“The Ballad of Ivor Punch”) or perky Afrobeat (“This Little Sister”). Best of the lot is “All The Love Remains”, a gorgeous confluence of his skills that portrays heartache with an acoustic sigh and a novelist’s gift for detail.
