Since this is not in poll form , I'll make my own nominees:
1960's - The Beatles........they changed everything about music , at their time. Classic , take them over the Stones any day of the week.
Honorable Mention: since......... The Doors....... were in the 60s and 70s , I want to put them here.
They were the "Guns N' Roses" of their time.Their music was ahead of their time , doing their own thing , with no rules or expectations.Jim died too soon
1970s - Led Zeppelin..........I'm not the biggest of fans , but I have to give them their due.
Everybody dug em , they were it in the 70s.
Honorable Mention: ...........Black Sabbath.......were that group that blew people away , Iron Man and Paranoid , are still 2 of the most popular songs of all time , most every band plays them as some of the first songs they play. Aerosmith was up there too
1980s - Motley Crue...........Van Halen fans , won't like this , but these guys were the definition of rock in the 80s , they were the stars of life , and everybody couldn't get enough.they were at their peak in 1989 , after capturing the rock world in 1983.
Honorable Mention:............That's Right........Guns N' Roses.............Axl and company hit fast and hard , they blew everyone away , and made a lot of fans during their tour with the Crue.They were fresh and welcomed by rockers everywhere and still have one of the largest fan bases in all of rock.
1990's - Guns N' Roses..........They held their ground when a lot of the 80s groups could not , people tried to bury them early to make room for grungeamatic , but they couldn't.
They wouldn't go away. sorry Nirvana , your 3 albums weren't enough , and everyone said Kurt Cobain was the new face of rock , now their are people who don't even know who he was..........
Honorable Mention............Pearl Jam...............Personally , I can't stand this group , but I will give them credit , they are a knat that just won't go away.Very popular with a lot of people.I do like "Daughter" , I will admit that , too!
2000's - This is the hardest , because no one has really reached out and yanked this title for me , yet. VR , is a possibility , we will have to see how Libertad turns out.
Nickelback is really dieing fast , their last 2 albums were not that good , IMO.
To be honest , I have not heard enough groups from this decade , so I'll say VR with a strong Libertad!
Honorable Mention: Hinder makes 2 more good albums in this decade...Watch out! Technically , I have no mention yet.
