There's a building material called Homosote that's an excellent sound 
absorber. It's a soft particle board with an uneven surface . You can find 
it at good lumberyards in 1/2" thick 4'x8' sheets for $25-$50. Asphalt 
sheets work well. Nothing compares to lead sheet but most inspectors treat 
it like asbestos so it's usually a bad idea.

Don't just insulate the walls- get the floor and ceiling too. The low 
frequencies will come right through the ground (especially if there's a 
concrete floor) unless you use isolation mounts and drop a sheet of sound 
absorbing material on the floor.

For serious sound isolation search on "build your own  recording studio". 
Most studio construction techniques are overkill for a garage but you're 
bound to find something useful.
