Way too many runner ups to list, but the six that hurt the most:
Despite having five truly great albums that are very different from each other, Stone Temple Pilots still get unfairly labeled as impostors and Pearl Jam knockoffs (they sound nothing like Pearl Jam). They had a perfect run from 1992 to 2001.
Sigur Ros would be a number one band for most letters. Kveikur might even be a top ten album of last decade.
System of a Down were so unique and explosive. Toxicity is their masterpiece, but there was a certain fire in that first album that I’ve never heard another band duplicate.
Sleater-Kinney and Sufjan Stevens are pretty self-explanatory. (The Woods and Carrie and Lowell are their best albums)
And finally, I can’t pass up another opportunity to go on the record about Sublime being great. Bradley Nowell knew how to write a song.
