Population Two stars such as those in Globulars are very light in metals so they are very long lived, as Trevor mentions population Three stars where massive stars,upto 150 solar masses or more but had only Hydrogen and Helium.
These stars have not yet been found, but could be found in the future with the James Webb Telescope
All today's stars have their metals due to past Supernovae
