The one thing that scares me about your situation is the pressure on your biking.
Here's my experience with stuff like that:
When I was doing alright, I was active from 7 to 23 o' clock, most often starting the day with a good paddling, and opening the shop afterwards. Sadly not everyone can decide over their time like that, but the point is I was active all day and having a blast at the same time. Though my music suffered badly during that period.
Quitting my daily paddling because of job pressure is what did me in, and I'm now heavily depressed and unable to attend my business well, and must concentrate on just regaining my health. Long story short: this thing has also cost me my wife and my house.
My take, of course: whatever you do, [b]do not compromise as to your biking[/b].
Biking will more likely give you the joy and the energy you need to be able to manage the rest of your day, including the band.
Best of luck!
