To be clear, I normally climb with a rope and partner. Free-soloing makes up only a small percentage of my total climbing. But when I do solo, I manage the risk through careful preparation. I don't solo anything unless I'm sure I can do it.
I suppose being a bit of an antisocial weirdo definitely honed my skills as a soloist. It gave me a lot more opportunities to solo lots of easy routes, which in turn broadened my comfort zone quite a bit and has allowed me to climb the harder things without a rope that I've done now.
Music can be useful during training to help get you psyched, and I still listen to music on easy climbs or in the gym. But during cutting-edge solos or really hard climbs, I unplug. There shouldn't be a need for extra motivation on big days, be it music or anything else. It should come from within.
I love my climbing shoes. Virtually all of my big solos have been in the TC Pros. They are the most important thing when I'm soloing.
Both Neil and I had done solo projects where we were the boss and I just thought that if he was willing to get into it, it would really be a good experience for him.
The whole time I was with 'The Temptations', I was accumulating my own solo recordings.
I'm not saying I'll never go solo - never is a long time - but I've always been onstage with someone else. That way, you're in it together, and you can feel, together, when the songs are right.
