The future of music cannot include record labels as we have them today.
If you need weird passport photos done (e.g. special sized US NI visa photos) - go to Passport Photo Services on Oxford St. No hassle, very quick and such weird requests handled without issue.
And did you know that Virgin on Tottenham Court Rd has a real music hardware section on the bottom floor? I'm pretty sure that it's fairly new, but they sell proper desks (Midas and Yamaha) and mics etc. It's all really expensive - but could be useful to have a look at before buying it from somewhere sensible.
