Review: Tonic – Knock Down Walls (Rock) Drew Wilson | March 2, 2016 This review covers the rock track Tonic – Knock Down Walls. This track was released in 1999 on the album Sugar. The lead guitars in this track definitely has a more or less unique quality to it. I thought this added a sense of originality throughout the track. The guitar chords added a nice soundscape throughout the track. The vocals were pretty good. They held their own nicely. They also clearly delivered the lyrics pretty well which is not always the case for rock tracks. Overall, I thought this was a great track to listen to. An interesting lead guitar, good chords, and good vocals made this track a good one to listen to. Score 8/10 Drew Wilson on Twitter: @icecube85 and Google+.
