The Quantum Light Breath CD is guided by Jeru Kabbal's voice with a number of musical selections and is an hour long. You can basically set your breathing rate to however fast or slow you'd like, which is sort of a disadvantage as you can slack off.
Sri Sri Ravi Shankar teaches a complex breathwork pattern but you'd have to learn it from one of his instructors or himself as it's not available on CDs.
Can't really recommend any CDs on Holotropic Breathwork. There are very few good CDs on actual practice of breathwork. Kelly Howell has a CD called Inner Fitness which is cenetered around the yogic Breath of Fire technique moreso than Andrew Weil's breathwork CD.
Perhaps the best breathwork CD on the market is from Sadhana Concepts and is called The Healing Art of Conscious Breathing. This technique was developed by Leonard Orr as Rebirthing. You can get this CD from amazon.com. It consists of a few 20 minute tracks that you can program for any length of actual guided breathing that you can follow. A novice will definitely attain altered states of consciousness in only a few minutes. Read the CD transcript at http://sadhanaconcepts.com/CDTranscript.html . And don't judge a CD by its cover.
