Jazz is covered by All About Jazz, Jazz Online, and Jazz Corner. Classical finds expression in Classical Net (check especially the links page). AMG covers all that and more. I get tabs from Guitar Tabs, Tabster, and Harmony Central. Drum licks from the Drum Network; online lessons from Learn2Drum and WebThumper.
