Smashing Pumpkins is my favorite band
Adore: truly a unique album, still ahead of its time, unappreciated, just beautiful. Highlight: 'For Martha'. Listen to it late at night, all the way through.
Mellon Collie and the Infinite Sadness: one of the most epic, daring cds ever as far as I'm concerned. Ranges from heavy metal, to classical-inspired songs. Highlight: 'And Ode To No One'
Saying that, "Siamese Dream" is still my favorite cd of theirs.
Otherwise:
Nine Inch Nails - The Downward Spiral (very organic sounding industrial. Highlight: 'March of the Pigs')
U2 - Achtung Baby (it's good ole U2 but in their best form. Highlight: 'One')
Depeche Mode - Songs of Faith & Devotion (good, emotional, spiritual album. Highlight: 'Mercy In You')
Elton John - Goodbye Yellow Brick Road (peppy album, Highlight: Grey Seal)
Green Day - American Idiot (an instant classic, Highlight: Boulevard of Broken Dreams)
Guns N' Roses - Appetite for Destruction (this album rocks hard, Highlight: My Michelle)
Korn - Self-Titled (pretty weird music, quite unique, Highlight: Blind)
Previously Mentioned
The Cure - Disintegration
Pink Floyd - The Wall
Any Tool cd
More recently, I thought The Dixie Chicks - Taking The Long Way is a really good cd. Great vocals.
