Records length and quality...

Muddy Waters' Folk Singer is about 32 minutes long... Gregg Allman's Laid Back 35... Bert Jansch and John Renbourn's Bert & John... 29 minutes... Martin Carthy's first on Fontana about 35 minutes...

All the above are - plainly said - seminal, music lighthouses discs and no one in the decades argued they've been too short and content-shy...

So what?

Quality or having a message is most important than giving to the market super-packed 70 minutes+ sometimes boring, overwordy, busy disks.
