Soma is of course, a song by the Smashing Pumpkins. I really didn't get into guitar in a big way until the 90's and Siamese Dream was an album that particularly blew me away. Soma, along with Mayonaise, remain two of my favorite songs. Soma (or variations on it when it's taken) has been my nickname ever since I heard that album. Sadly Smashing Pumpkins released 4 good albums and then (IMO) went downhill fast.
Side Note: I listened to guitar music before the 90's, Metallica, Iron Maiden etc but it was Nevermind that really grabbed me by the balls and made me think 'I want to be a guitar player'. Strange when you consider Cobain's style, but oh well
Cheers.
