Here are some podcast suggestions that I listen to regularly:

The psychedelic Salon is a podcast made by Lorenzo who was ‘there’ in the centre of the psychedelic revolution, and carries this flame all the way to the future. Make sure you listen to the McKenna tapes, but there is a lot more going on here!

Hardcore History is a podcast by Dan Carlin. I think this is by far the best history podcast I have ever heard. If I had a source like this in high school, I would have probably studied history! The shows are hours at a time and take you right there at the frontline of the psychological drama.

Joe Rogan hosts one of the most populair podcasts in the world, and for a good reason. Its funny, serious and his guest are from all walks of life.

Sam Harris has a nice podcast with great conversation on a variety of sensitive subjects.

On Being is a podcast in the same line, although it is a little more about the story of the guests than merely conversation on topics.

Sodajerker On Songwriting is, well, about songwriting. The guests are among the most famous artists in the world, and they really appreciate the craft and work involved in writing music.

No guitar is safe is a podcast that have some serious guitarplayers from all over the world. Jude Gold hosts the show, and always jams with his guests, which is awesome!

Wong notes is a podcast by Cory Wong. He has great gitarists on his show, that sometimes give interesting perspectives on being a musician. Its an easy listen.

Hanging out with audiophiles is a podcast by Jamie Lidell. Whats not to love about it. He is amazing in much every respect, and his guests are top line producers that share there insights on writing, producing and mixing music.
