Problem: Background: Sir George Henry Martin (3 January 1926 - 8 March 2016) was an English record producer, arranger, composer, conductor, audio engineer, and musician. He was referred to as the "Fifth Beatle", including by Paul McCartney, in reference to his extensive involvement on each of the Beatles' original albums. Martin produced 30 number-one hit singles in the United Kingdom and 23 number-one hits in the United States. Martin produced comedy and novelty records in the early 1950s, working with Peter Sellers, Spike Milligan, and Bernard Cribbins, among others.
Context: Martin was born in Highbury, London. When he was six, Martin's family acquired a piano that sparked his interest in music. At eight years of age, Martin persuaded his parents, Henry and Betha Beatrice (nee Simpson) Martin, that he should take piano lessons, but those ended after only eight lessons because of a disagreement between his mother and the teacher. As a child, he attended several schools, including a "convent school in Holloway", St Joseph's School (Highgate), and at St Ignatius' College (Stamford Hill), where he had won a scholarship. When WWII broke out, and St. Ignatius College students were evacuated to Welwyn Garden City, his family left London, and he was enrolled at Bromley Grammar School. I remember well the very first time I heard a symphony orchestra. I was just in my teens when Sir Adrian Boult brought the BBC Symphony Orchestra to my school for a public concert. It was absolutely magical. Hearing such glorious sounds I found it difficult to connect them with ninety men and women blowing into brass and wooden instruments or scraping away at strings with horsehair bows. Despite Martin's continued interest in music, and "fantasies about being the next Rachmaninov", he did not initially choose music as a career. He worked briefly as a quantity surveyor, and later for the War Office as a Temporary Clerk (Grade Three), which meant filing paperwork and making tea. In 1943, when he was 17, he joined the Fleet Air Arm of the Royal Navy and became an aerial observer and a commissioned officer. The war ended before Martin was involved in any combat, and he left the service in 1947. Encouraged by Sidney Harrison (a member of the Committee for the Promotion of New Music) Martin used his veteran's grant to attend the Guildhall School of Music and Drama from 1947 to 1950, where he studied piano and oboe, and was interested in the music of Rachmaninoff and Ravel, as well as Cole Porter. Martin's oboe teacher was Margaret Eliot (the mother of Jane Asher, who would later become involved with Paul McCartney). After that, Martin explained that he had just picked it up by himself. On 3 January 1948 - while still at the Academy - Martin married Sheena Chisholm, with whom he would have two children, Alexis and Gregory Paul Martin. He later married Judy Lockhart-Smith on 24 June 1966, and they also had two children, Lucie and Giles Martin.
Question: what other instruments did he play
Answer: Despite Martin's continued interest in music, and "fantasies about being the next Rachmaninov", he did not initially choose music as a career.

Background: Darrell Lance Abbott (August 20, 1966 - December 8, 2004), also known as Dimebag Darrell and Diamond Darrell, was an American musician and songwriter who was a co-founder of Pantera alongside his brother Vinnie Paul, and founder of Damageplan. He was considered to be one of the driving forces behind groove metal. Abbott was shot and killed by a gunman while on stage during a performance with Damageplan on December 8, 2004, at the Alrosa Villa in Columbus, Ohio. He ranked No. 92 in Rolling Stone magazine's 100 Greatest Guitarists and No. 1 in the UK magazine Metal Hammer.
Context: On December 8, 2004, during the Devastation Across The Nation tour, Abbott was shot on-stage while performing with Damageplan at the Alrosa Villa in Columbus, Ohio. A crowd of approximately 250 had watched four support acts (two local bands entitled Volume Dealer and 12 Gauge, and the tour support Shadows Fall and The Haunted). Moments into Damageplan's set, 25-year-old former Marine Nathan Gale shot Abbott five times in the head with a 9 mm Beretta 92F pistol. Some in attendance initially believed the shooting was part of the act, but as Gale continued shooting, the audience quickly came to the realization that the event was not staged. Firing a total of 15 shots, Gale killed three other people and wounded seven more. Jeff "Mayhem" Thompson, the band's head of security, was killed tackling Gale, as was Alrosa Villa employee Erin Halk. Audience member Nathan Bray was killed while trying to perform CPR on Abbott and Thompson. It was rumored that one crowd member leapt in front of the gunman, saving the lives of several band members. Damageplan's drum technician, John "Kat" Brooks, was shot three times as he attempted to disarm Gale, but was overpowered and taken hostage in a headlock hold. Tour manager Chris Paluska was also injured. Responding within three minutes to a dispatch call made at 10:15pm, seven police officers entered through the front entrance and moved toward the stage. Officer James Niggemeyer came in through the back door, behind the stage. Gale only saw the officers in front of the stage; he did not see Niggemeyer, who was armed with a 12 gauge Remington 870 shotgun. Niggemeyer approached Gale from the opposite side of the stage past a group of security guards, and saw Gale lift his gun to Brooks' head, and fired a single shot as Gale noticed him. Gale was struck in the face with eight of the nine buckshot pellets and was killed instantly. Gale was found to have had 35 rounds of ammunition remaining. Two fans, including Mindy Reece, a certified nurse, administered CPR on Abbott until paramedics arrived, but were unable to revive him and he was pronounced dead at the scene. Early speculation about motive suggested that Gale, who was a Pantera fan, might have turned to violence in response to the breakup of the band, or the public dispute between Abbott and Pantera singer Phil Anselmo, but these were later ruled out by investigators. In VH1's documentary, Behind the Music, Damageplan's sound engineer Aaron Barnes stated that the whole time, after shooting Dimebag, Gale was looking for Vinnie, possibly planning to murder him too. Another conjecture was that Gale believed Abbott had stolen a song that he had written. About six months prior to the shooting, Gale got into an altercation at a Damageplan concert in Cincinnati where he damaged $5,000 worth of equipment while being removed from the stage by security.
