 Who biographer John Atkins wrote that the group 's early test sessions for Pye Records in 1964 show that " they seemed to have understood just how important was ... Moon 's contribution . " Contemporary critics questioned his ability to keep time , with biographer Tony Fletcher suggesting that the timing on Tommy was " all over the place . " Who producer Jon Astley said , " You didn 't think he was keeping time , but he was . " Early recordings of Moon 's drumming sound tinny and disorganised ; it was not until the recording of Who 's Next , with Glyn Johns ' no @-@ nonsense production techniques and the need to keep time to a synthesizer track , that he began developing more discipline in the studio . Fletcher considers the drumming on this album to be the best of Moon 's career .
