Grunge is dead shirt-WHAT DOES THAT MEAN

Well,when Kurt used this shirt,it was something,ironic.... But the years has passed, and this phrase isn't so ironic anymore. Since Nirvana died,grunge doesn't have a on rock music, its not popular,that is bad. Its bad cause grunge is almost dead. So grunge only hope is bands like: Pearl Jam,Alice in Chains,Melvins,and others bands
