The first time I ever heard Cloud Boat was 2 years ago when they were the support act for James Blake. And ever since seeing them live I have 'watched the space', waiting patiently for their debut album. And now that it's out, I couldn't be happier with the result.The album's dreamy, eery, soft sound is much lighter compared to James Blake's, and a couple tracks immediately stand out for me. "Godhead" and "Dréan", being the most gripping, stand out for their gentle, acoustic sound and for being the vocally best songs on Book of Hours."Bastion" also stand out for me as it starts very calm and gentle, much like "Dréan" and "Godhead". But it then switches up into a fantastic mix vocal sample, Guitar riffs and heavy drumline. "You Find Me" is also one of the best songs on the album, in my opinion, but is criminally short.And finally, album closer, "Kowloon Bridge" which reminds me a lot of "After the Storm" by Mumford & Sons (Ironically, the last track on their debut album Sigh No More).The only bad point on the album for me is "Amber Road", which sort of sounds like James Blake's "Not Long Now" on a bad acid trip. Not saying that "Amber Road" is bad, but its much darker and more 'dubsteppy' sounding than the rest of the album. Making it stick out like a sore thumb the same way "Wild for the Night" did on A$AP Rocky's Long.Live.A$AP.Overall, this album is fantastically produced, written and performed. I definitely recommned it to anyone who is a fan of James Blake or have heard some of Cloud Boat's stuff. I am now a fully devoted fan of Cloud Boat and hope they achieve higher levels of success and gain more recognition for their sound.
