When I was taking lessons years ago I really began to appreciate Jazz. I learned a lot from my instructor. I still noodle around with it today to some degree.
But, there's nothing like plugging in and playing bands like the Buzzcocks, LOVE me some All/Descendents (Stephen Egerton is a wiz), your staple HC band such as Minor Threat, Quicksand, Bad Brains, anything and everything Rev related (I am partial to Chain of Strength, GB, Nerve Agents). Basically anything and everything.
What about you?
