This is a fun poll...
So, Rush is my favorite band, but I can't say it's because of their first four records ("Sector 1", so to speak)
I mean, I enjoy all of them, really, but that's not desert-island material for me...
Metallica could well be in the running. Still close to my musical heart and my very first (truly) heavy music love. And that 4-album run is unbelievable.
VERY fond of Aerosmith too - as a youngster, I discovered them with their end of 80s/early 90s records Permanent Vacation and Pump (still big favorites of mine) but, going back, their early albums are undeniable. Get Your Wings/Toys/Rocks especially. They are just not
quite up there as a band to be desert-island, I guess.
Queensryche's run is something else too. Excluding the EP, I'd take the Rage through Promised Land run over The Warning though Empire (I know, I know), but still. The Warning/Rage for Order/Operation:Mindcrime/Empire. Hard to argue with that...
...But, but. My top 4 Dream Theater albums are as follows:
1) Images and Words
2) Awake
3) When Dream and Day Unite
4) Falling Into Infinity
Yes, I absolutely love both WDADU and FII, with all of their imperfections.
And DT are my #2 favorite band. Soooo...I guess it's a pretty obvious choice for me in the end. Dream Theater it is!
