Heres some of my favourite music groups/bands:
3DoorsDown-all albums good, and with really good lyrics.
Disturbed(metal). Like all theire albums.
Bigbang-Norwegian band playing some really cool-new hippie styled rock.
A perfect circle. The song "outsider" is awesome, but they got a few more good ones.
Monster Magnet. the song "Spacelord" is uber cool, but i didnt like the rest of the repertoire.
Sepultura: They got a cover song called "orgasmatron". Originally Motorhead who has it.
Biffy Clyro. "many of horrors" and "the captain"
Breaking Benjamin. "the diary of Jane" and "Breath"
White Lies. A pretty new band ive discovered, and i really like both realeased albums. Listen to the lose my life album first.
H-Blockx. albums time to move and fly eyes are really good.
Kaizers Orchestra. From Norway also and they use alot of different instruments. Can recomend the song called "maestro" and "knekker deg til sist" but they have many really good ones, so check them out if you can bare singing in Norwegian
A few new bands i started to listen to recently are "Foster the people" and "Delta spirit". Really like both of those. Started to like them when i saw the live consert from Lollapalooza.
El Caco. Really good norwegian metal. Check out "the glow" "am i wrong" "substitute" "grinding the diamond" and "someone new"
Janove Ottesen: Norwegian solo artist. Lead singer in kaizer orchestra
Default. Great band from Canada. I love all thire albums.
Stone Temple Pilots. Check out the album "core". One of my best albums
Temple of the Dog. Eddie wedder and chris cornell. whole album is great.
Span. Norwegian metalband. The album Mass destruction is very good. Check out lead vocal bernhoft solo album "ceramic city". its jazzy
Theres so many other groups/bands i like, but many are well known to most. I will update later when i remember other good ones.
