 Keen to pare down the production after the Wall of Sound excesses employed by Phil Spector on All Things Must Pass , Harrison used a small group of backing musicians throughout the sessions . Aside from himself on electric guitar , the line @-@ up on the basic track for " Living in the Material World " was Nicky Hopkins ( piano ) , Wright ( Hammond organ ) , Klaus Voormann ( bass ) and Starr and Jim Keltner ( both on drums ) . Inglis describes the music as " a powerful rock backing " , while Leng views " Living in the Material World " as " the one time in his career that Harrison deliberately set out to create a big , showpiece rock number " .
