No, you are just very narrow in your knowledge. If you haven't heard of Gryff Rees (Super Furries), Richard Hawley (Longpigs), Latitia Sadier (Stereolab), and Bill Ryder-Jones (The Coral) your knowledge of music is very limited being as all have been in rather well known bands and have had extensive solo careers since leaving those bands.
Slowdive are one of the original shoegaze bands
Yo La Tengo have been going forever and have an extensive back catalogue, last album was superb
Sleater Kinney?
You really claiming you've never heard of Baxter Dury?
If you haven't heard of Ty Segall you've never read many music posts here
It's also got an awful lot of up and coming, potentially much bigger bands like English teacher and Big Special. Warrington Runcorn New Town Development Plan is the current king of ambient electronica. House of All are all ex-members of different periods of The Fall and are ace.
Its a really good line up. I'd have conflicts of scheduling all over the place
