How would the 90's be affected if Oasis had never formed? Maybe Noel falls out with Liam earlier and goes solo or forms a new band?
How would this affect Britpop and the other bands who formed/changed their style (Lush, Ocean Colour Scene, Ride) to accommodate the new music scene?
Bonus points if:
- Blur remain as a Shoegazing band
- None of the lame piano bands of the early 00's exist
- You can detail how Grunge is affected
It's worth considering that some big early 1990s madchester/shoegaze bands had already released transitional albums before Oasis put their first single out - Blur's 'Modern Life is Rubbish' & The Charlatans 'Up to our hips' were key signs that the smarter bands were looking to reconnect with classic British rock & pop.
Even a heavy shoegaze band like Ride was doing it - their 1992 album 'Going Blank Again' was very pop-influenced.
Then you have bands like the Stone Roses & Happy Mondays who were basically sabotaging their own careers well before Oasis landed in the charts. It's too late to save the Mondays, but it's possible that with no Oasis the Stone Roses make a better impact on their return.
Another possibility is that another band leads Britpop that draws key inspiration from a different 1960s band. We already have a Kinks-influenced Blur well under development by 1994, but there's also Ocean Colour Scene moving away from indie-dance and towards late-Small Faces/Traffic r'n'b,
Also, the Stairs recorded an album heavily influenced by the Rolling Stones (Their single 'Weed Bus' was a remarkable blend of Stones & The Who)

One last idea is that if Blur get a different producer - lets say the label insists on Mick Jones from The Clash/Big Audio Dynamite or Tina Weymouth/Chris Frantz back out of producing that Happy Mondays album, and end up working with Blur instead - then you potentially get more hip-hop influences in there earlier.. (think Gorillaz, or the 13 & Think Tank albums by Blur) which could make for some success in the USA post-grunge. You might get more creative tension between Damon & Graham, though.
