Porcupine Tree.
The 'floyd' of the 90s.
Amazing band , their leader/singer/guitar player/songwriter/producer Steven Wilson is a ****in genius.
Funny thing is , they made their best albums in the 90s when they were hardly known and they finally began to get some (much deserved) recognition in the 00s when their sound turned almost prog metal and the albums weren't nearly as good as the 90s batch
Having listened to them for more than 15 years, i say this may be the band you're looking for
i will do a mini-review of their 90s stuff (i may be a newbie in phones ,but music is another matter
)
if you like the more psychedelic feel of floyd you should definitely grab these 3 , which may be their best work (in my mind at least they are)
THE SKY MOVES SIDEWAYS (1995) : Probably their work so far , a lost classic of the 90s .Essential crap.
UP THE DOWNSTAIRS (1993) : More 'dreamy' than sky , but (almost) equally good. Like wish you were here with less melancholy.
SIGNIFY (1996) : Less psychedelic and more prog , this closes their best 3-album span.
I would also recommend their next 2 albums , which enter more into Beatles song-oriented albums
STUPID DREAM (1998) : More melodic than psychedelic , this is imo thier last truly great album.
LUGHTBULB SUN (2000) : Their last Phase-1 album , good to very good but not great . You will probably get it after done with the previous 4 i have mentioned.
These 2 are also very very good , 1 live album best-of from their 93-96 catalogue and one EP which is as close to run like hell without being run like hell
COMA DIVINE (1997) : Live album from their signify tour , apart from being an excllent live album this is like a best-of collection from their 1991-96 period , which imo is their best,most fertile and most accomplished in the album/songwriting department
VOYAGE 34 : A 64-minute (!) EP about the adventures of Brian , which has a bummer in his 34th LSD trip.
When people say Radiohead are UK's best 90s band , i laugh like a madman...If there was music justice Radiohead would open for porcupine tree every single night....
Invest in them and rpepare for a mental rollercoaster filled with melody and emotion.
