Sleepmakeswaves are a little known instrumental post-rock band from Sydney, Australia. Like most post-rock bands, they combine slow melodies with crescendos and intense climaxes. But their variation comes from use of multi-instruments and hints of genre-bending, from powerful metal-like drum sequences to ambient electronic bridges. Their debut album In Today Already Walks Tomorrow displays the band's range of style and sound.
Opening track 'I Will Write Peace On Your Wings and You Will Fly Over the World' Starts off unusually for a post-rock song, as it begins with a climax-like intensity, then simmering down only to build right back up again. The instrumentals here are top-notch, creating a range of intensities that make the song exciting. 'One Day You Will Teach Me to Let Go of My Fears' climaxes in the middle, combining a nice build-up with a smooth, easing tempo into a quiet finish. 'It's dark, It's cold, It's winter' is just really nice, simple ambient music.
In Today Already Walks Tomorrow is a great post-rock album and I highly recommend it to any fan of the genre. Also check out their self-titled EP, they're both free.
