Tough job to narrow it down to seven songs, but I'll give it a crack.
There are two albums at the start of the decade that defined the direction of 'traditional' heavy metal, that made the jump from the 80's into the 90's with a bang. Song #1 is the title track from one of those albums, Skid Row's 1991 release "Slave to the Grind". How do you go from the fun hair metal sound of their debut, to the riffingly brilliant heavy sound that punctuates this song and this album? What a jump. Everything clicks here. It's just such a shame of what became of this. It should have been the springboard to mega success. Instead, mediocrity awaited.
Today I nominated Anthony Fulton to get off his arse, fire up his Spotify and start showing us what he recalls from the '90's. But it probably won't happen.
