By his teens, he was already recording top Jazz artists of the day; this included names such as, Kathy Stobart and Ian Carr.
[6] It was this band, with local guitarist Mick Abrahams, drummer Clive Bunker and bassist Andy Pyle that formed the foundation of Jethro Tull which, with the addition of multi-instrumentalist Ian Anderson, went on to sell over 60 million albums.
[8] The SRT studios moved from Luton to Shefford, Bedfordshire where facilities included mastering lacquers for vinyl manufacture.
[9] Local folk rock bands that recorded there included Back Alley Choir,[10] and Halcyon, the drummer of which was Nigel Pegrum, who went on to join Steeleye Span.
Apart from music production, SRT was one of the first manufacturing brokers, and had a close relationship with Abbey Road Studios, where artists were encouraged to attend cutting of the pressing lacquers for their forthcoming vinyl releases.
He thus achieved RCA's quality goal, helping the factory to gain further substantial clients including Virgin and Island.
In addition to his work on commercial audio products, he was also a leader in creation of the first 20-bit recordings and an early exponent of Sony's Super Bit Mapping noise shaping.
With a team of staff under his supervision, he recorded over 120 high bit classical albums with the Royal Philharmonic Orchestra, working with some of the world’s leading performers and conductors, such as the late Yehudi Menuhin and Sir Charles Mackerras.
In 1997, he and his music team collaborated with Buckingham Palace to produce the official recording to commemorate the decommissioning of HMY Britannia.
The recording was of British music performed by the Royal Philharmonic Orchestra and Chorus conducted by Carl Davis; it includes material such as "Coronation Scot", "Jerusalem" and "Rule, Britannia!".
Recent projects include work for Demon Music Group, (a division of BBC Worldwide) preparing masters for new CD, online and vinyl releases that include Average White Band, Squeeze, Buzzcocks, Rick Wakeman, OMD, Ten Years After, Uriah Heap, Spandau Ballet, Gary Numan, Fairport Convention, Asia, Lindisfarne, Sad Café, The Strawbs, Belinda Carlisle and Wishbone Ash.
In September 2015, Richardson featured in a programme broadcast on BBC Radio 4, where he spoke about the early history of SRT's studio in Luton.
