Tip o' the week - Breaking away from the blues
If you can play a few different styles, you'll have more chances to play! Straight-harp styles can be incorporated in country, bluegrass, and other roots styles, and if you could play like Lee Oskar with War or Magic Dick with the J. Geils Band, rock bands would be more than happy to let you sit in. The blues is king (!), but don' t be surprised if not everyone wants to hear your best Little Walter licks. There is a lot of great music that can use some tasteful harp work, so don't limit yourself to just your favorite styles if you really want to play in front of people.
