Tower in Boston opened while I was attending Berzerklee School of Music which was one block away. The building was designed by famous architect Frank Gehry, and had the largest classical record display anywhere, iirc. CDs were just coming in, but it was still a novelty. 3 gigantic floors of music, probably >10,000 sf per floor. Jazz and world music on top floor, classical in the middle, pop and rock on the first floor. Between Tower and Looney Tunes used (and cutout) record shop we had it made in the shade.
The Tower explosion was fueled by the peak in record sales, which was caused by the peak in popular music quality. It all fell down when the business went digital, allowing easy music theft and DIY record producers to make rap. Both of which dissueded long term investment in talent development, so the whole thing dried up. The final bullet was video games, Mario Brothers on Nintendo stole the attention of kids who would otherwise have stay with music as their primary entertainment. Video killed the Radio Star. But it is all natural evolution. Change happens!
Thanks for the heads up, Tom
