How Can I Convince my parents to let me???

hey so this is anon bcos im just mega embarrased, so please keep it that way! ok, so basically, i do have friends and im happy in that regard, but basically i have a friend who im going to see a gig with at brixton in a couple weeks. but now he can't go :( no one else likes the band im seeing, so to be honest i kinda want to go on my own. ill have fun honestly it doesnt bother me! but the issue is my parents wouldnt let me go on my own :( so how can i formulate a plan to make them not find out? DESPERATELY NEED TO SEE THIS BAND OMG
