Watch the Green Groove online guitar lesson by Matthieu Brandt from Chord Tricks For Electric Blues
In thick arrangements or when you're playing uptempo, it doesn't make any sense to play full barre chords or chords with extensions. You'll take up more space, which your fellow band members won't like. Rhythmically and harmonically, you'll have to do less. Find a specific rhythmic pattern or stay in line with what the bass player is doing and undress the chords you're playing.
