Today's episode marks a quarter-century milestone for Tracks, and we celebrated the only way we know how - with a few beers and a lot of music chat.

The release day also happens to be the anniversary of the legendary collaboration between The Beatles and Eric Clapton on George Harrison's classic 'While My Guitar Gently Weeps'. With this in mind, we decided to take a look at some of our favourite tracks which feature other artists. Spoiler alert: Nas, Edwyn Collins and SBTRKT are amongst those who receive shoutouts.

Away from the features, we also have our traditional musical highlights of the week. This time around they're courtesy of The Avalanches and Foals, both of whom have got us particularly excited this week.

So sit back, marvel at the magnificence that is Tracks' first block of 25 episodes and, most importantly, enjoy a trip back to the feature.
