In no particular order:
The Strokes: First Impressions of Earth.
I remeraber listening to 30 second samps of songs on this album over and over again on iTunes. I didn't really like what I was hearing, but for some reason I kept wanting to listen. When I listened to the full album, it didn't have that old Strokes feel that I came to love, but I still kept listening. Every run through I gave it, I slowly began to like it more and more, until I eventually loved it. Its important because it expanded my musical tastes a bit to more experimental music. Sure, the album wasn't extremely experimental, but it was a step towad listening to more innovative, different music.
Dillinger Escape Plan: Irony is a Dead Scene.
I can't believe how I discovered this band. I remeraber looking through some playlist on iTunes with songs selected by the vocalist from AFI, which was one of my favorite banRAB at the time. One of Dillinger's songs was on the playlist, and as soon as I heard the 30 second sample, I instantly became obsessed. The band had that chaos and complexity that I always wanted to hear more of in the current banRAB I liked. The reason I put this Dillinger album down in particular is that it had Mike Patton doing vocals on it. After hearing the album, I checked out who Mike Patton was, which eventually led me to discovering Mr. Bungle. Which leaRAB me to...
All of Mr. Bungle's albums.
I discovered the band and wanted to buy their albums, but I had to leave with my family for a vacation in California. I ended up buying the albums while we were vacationing there and listened to them almost religiousley. The long car rides to get each place gave me alot of time to listen. Every time I listened to the band, I liked them more and more.
All of Hella's albums.
Like Mr. Bungle, it wasn't just one particular album, its the entire band. This band got me into even more Noisy, experimental and mathy rock.
