Rock album covers and their image

I looked at some album covers of the three different genres our band cover; rock, progressive

Rock

 This is a very typical rock album cover. The lead singer is in the middle of the group, with the guitarists/bassists to his side, and the drummer in the back. It's the setup you would see at a concert or gig, and the picture denotates them playing live. Their hairstyles definitely meet the 'rocker' expectation. Black and long, the typical convention associated with rock. Also their clothing, black jeans, leather jackets, belts and chains, also depict the same message.The artists poses signify quite an old, traditional rock image, that I doubt would be used in this day as an album cover, as times have changed, and rock has modernized.

Progressive Rock

 

Here is an unusal album cover.It clearly shows 4 men, dressed "oddly" sitting round a dining table in an unusual location. It looks like a very hot desert or another planet perhaps, maybe mars considering the red colour. Also the album is called "Black Holes & Revelations" so the extra-terrestrial planet can relate to black holes. Also it seems that the men and the table are the only objects in that area, surrounded by a lot of sky and space, with space again relating to black holes. The 4 men are wearing unusual, eccentric clothing - shiny and wild, colourful suits. This represents Muse's music and how different they are. Muse and their music genre have the ability to be different and not follow orthodox genre conventions.

Alternative Rock

The album cover is in black and white (apart from the band name text) this makes it seem retro and vintage. Which meets genre expectations. On the right you see 2 of the artists, kneeling, with 1 trying to perform a medical action of pumping the chest. Along with the person laying on the floor clearly looking knocked out, this medical action also proves hes knocked out/ unconscious. The man on the left draws a lot of attention to himself as his face is lit up and holding his hand out as if signalling "stop". This shows he acknowledges the camera which is taking the photo, and my implication of this is that the person taking the photo is a photographer/paparazzi and is taking a photo of the aftermath of the night out these men endured. And because it seems like quite a controversial night out (unconscious man on the pavement) the man on the left is trying to prevent the photo being taken. 

Quite a confusing/ interesting album cover because they're all wearing formal suits, and you don't associate this apparel with folk laying unconscious on the side of the road. You could intepret he has passed out because of an intense night involving copious amounts of alcohol, which can be associated with the heavy, rock lifestyle in which they party and drink a lot. However this is different, thus giving an edge, or difference over the typical rock conventions.
