Best new songs of the week

Caspian stay on the well-known post-rock path 'Flowers Of Light', but it's stilly just pleasing music; Moses Sumney is something totally different on 'Virile' - modern take on folk-soul, he directed the video himself (watch below); Trail of Dead decided to make pop-song music - 'Don't Look Down' is such; Modest Mouse seem young and fresh on 'Ice Cream Party'; Grimes' new song 'So Heavy I Fell Through The Earth' is ambient and poppy, promising; Japanese screamos Envy have an intense-meets-pretty song out - 'A Step in the Morning Glow'.
