of drums or percussion, Geraint's energetic guitar style contributed at least as much to the rhythm as to the harmony of the group. The quartet of Geraint, Graham, Dafydd and Gwyndaf recorded two albums, Ar Log II and Ar Log III. The former album contains perhaps the best example of the Roberts' brothers harping: "Merch Megan/Wyres Megan" and "Llydaw" are two classic triple harp arrangements. These contrast with sea shanties of J. Glyn Davies ("Fflat Huw Puw" and "Rownd yr Horn"). In 1983, Ar Log's horizons expanded substantially with the addition of Stephen ('Steffan') Rees (accordion, fiddle and keyboards). Ar Log's instrumental polymath, Stephen went on to lead an academic career in music. Rees played clarinet on one track ("Ciosg Talysarn"). Pritchard left in 1983. By this time, Ar Log had become particularly associated with Dafydd Iwan, a long-standing figure in the Welsh national movement. In 1982 and 1983, Ar Log embarked on two tours with Iwan. The first tour 'Taith 700' was to mark the 700th anniversary of the death of Llywelyn ap Gruffudd in 1282. The tours produced two albums (Rhwng Hwyl a Thaith and Yma o Hyd). The synthesiser and accordion of Stephen Rees came to the fore for the first time on these two recordings. On some tracks, the synth would comprise simple, sustained background chords (e.g. "Dail y Teim"). On others, synth would be used to specific effect e.g. harpsichord sound ("Abergeni") or trumpet fanfare ("Yma o Hyd"). The accordion medley on the Yma o Hyd album with its proliferation of triplet notes remains perhaps the most complex set performed on Welsh accordion to date. In 1983, the group recorded an all-instrumental album, Meillionen (=clover leaf), aimed primarily at the Welsh folk dance community. Dafydd Roberts is a skillful clog-dancer. The sleeve notes of the album also included a booklet of dance steps for the various sets on the album. Meillionen is the only non-eponymous album in the set. Ar Log IV was recorded in 1984. Ar Log's ability to convert simple tunes into sophisticated harmonies is demonstrated in tracks such as "Cerrig y Rhyd". By 1988, Iolo Jones had returned as a second fiddler. Ar Log V probably remains the group's most prominent album in terms of blending the synthesiser into the traditional elements. The group also rejoined Dafydd Iwan in 1988 for a celebration of the singer's quarter-centennial on the road. However, by
