The singer, who recently recorded an album with terminally-ill Dr Feelgood guitarist Wilko Johnson, said he had "a million things" he still wanted to do.
He said: "I want to do as many records now in this last bit of my life, even if I just get them into the can, in as many styles, because there's a huge amount of my voice that people haven't heard.
"I mean I used to sing Howlin' Wolf in 1963 and Johnny Cash in 1963 and Roy Orbison in 1963. You can't get more different sounds. Those bits of my voice the public have never heard."
Daltrey, who announced the line-up for the Teenage Cancer Trust gigs in March, said he hoped to get Johnson involved but added that the musician's cancer meant they could not make any plans.
He said: "We've got a show planned for the25th of February but you've got to understand that, at the moment, this thing inside of him is as big as a grapefruit and getting bigger every day."
Daltrey said the recording was not a "grim" experience despite the state of Johnson's health.
He said: "Both him and I are very philosophical about death. We sadly live in a society that is in denial of it. It doesn't frighten me at all."
