"While the tell-tale Swedish rock aesthetic is prevalent throughout all 13 tracks, the four-piece manages to push out some heavier than expected moments, as on “Black Dawn” and “Rise Above.” Both tracks have a rumbling tone that falls between the syrup of Acid King and the pile-driving mayhem of Black Cobra and are immediate highlights of Come Heavy Sleep. There's a bit of radio sensibility – in both the vocals and the composition - to Deville as well. Come Heavy Sleep does the job of laying down some kick ass stoner rock. Lots of good songs on this one."
"The C.O.C., as well as the KYUSS desert rock influences are continuously present, evidenced by the warm grooves that reverberate throughout the disc. Add a little bit of a 90's alt rock flavor, (SOUNDGARDEN, NIRVANA, etc…) and you've pretty much nailed the DEVILLE sound."
"Take some groovy rhythms, buzzing guitars and tight drumming and slap a whole bunch of guitar solos on it and use the word ‘baby’ a lot and you’re looking at an album that will help get every self-respecting stoner fan through the day. Yes, the spirit of Kyuss shines strong in this one, young Padawan. But there’s more shining on this album here… these guys aren’t afraid to take their foot off of the gas pedal every now and then – like on “Sweet Blood” - and the result is just as impressive as everything else on “Come Heavy Sleep”."
