The band was formed in Birmingham by Richard March, formerly with the group Pop Will Eat Itself, and Mike Stokes, with guest appearances by James Atkin, a member of indie band EMF. "Both more or less penniless, they drank in the same pub and were forced to buy their records at the cheapest place possible - car boot sales". Their live drummers were Keith York and Fuzz Townshend, alongside whom March previously played in Pop Will Eat Itself.
A second album, For Your Ears Only, was released in 2000 on Parlophone but was less popular. A further single "Madam, Your Carriage Awaits" was released. The group also compiled a two CDFSUKcompilation album. In 2004, the Bentleys released a 4-song record with Sophia Lolley called Angel Face.
The name probably refers to the Rhythm Ace line of analoguedrum machines manufactured by Ace Tone, some of which were rebranded and distributed by Bentley Pianos in the UK.
The group epitomises the big beat era. Signed to Skint Records, they enjoyed commercial success with their music being used on television advertisements and having an underground following.
The group split in 2000, but they played the occasional low-key DJ set. However, in 2009, they reformed and managed by Cut La Roc signed to Rocstar Records.
