Pink Floyd - Let There Beeb More Light 1967-1974 [5CD] (2014)

"Depending how you count, the Pink Floyd performed live on BBC Radio or Television a little more than a dozen times between 1967 and 1974. Their first two radio sessions, both on the programme Top Gear, featured original bandleader Syd Barrett on guitar and vocals, as did BBC-TV appearances on Look Of The Week and Top Of The Pops. All BBC performances after 1967 would feature Barrett's replacement, David Gilmour in the guitar/vocalist role.

"Let There Beeb More Light collects all surviving and circulating performances by the Pink Floyd at the BBC from their respective best sounding sources in chronological order. Now can be heard Pink Floyd’s evolution from psychedelic pop to progressive rock grandmasters in six discs worth of rare music."

In short, the idea is that this is all of Pink Floyd's BBC material from the best sources, as of earlier this year.

One thing to note is that in 1975 (Disc 5), the BBC broadcast a set of Pink Floyd playing "Dark Side of the Moon" at Empire Pool from 16 November 1974. Pink Floyd played there for four straight nights, playing two sets each night: one of "Wish You Were Here" material, and another of "Dark Side". The band recorded at least both sets from 15 and 16 November, and perhaps all of them. An edit of the two performances from 15 and 16 November were released on two separate discs on the "Dark Side" and "Wish You Were Here" Immersion collections. From what I understand, it was the band who recorded the performances and owned the tapes, and licensed the 16 November 1974 set for broadcast on The Alan Freeman Show on the BBC. (Please correct me if this is wrong!)

The decision, then, was made to only use the single set from 16 November 1974 as broadcast by the BBC, and not the two sets edited from the 15-16 November 1974 shows as released on the Immersion box sets. Which is just a long-winded way of saying "that's why the Harvested bootleg was used as the source for Disc 5 and not the Immersion collections."
