I would say The Stone Roses as well but their best songs were released in 1989. They still influenced a lot of the big 90's Indie bands. I suppose The Smiths as well would count as influences but I can't stand Morrissey. His lyrics are overrated and he has the worst recorded voice in the history of music.
90's Indie was my era and the main names that stand out are... probably in order as well for me.
Oasis
Radiohead
Blur
Pulp
Stereophonics
Ocean Colour Scene
The Verve
James
Supergrass
Muse
Shed Seven
Cast
Placebo
Suede
