IF, LIKE me, your evening from around 7pm-9pm, Monday until Thursday, tends to orbit around listening to Marc Riley's BBC6 Music radio show then you'll know of his penchant for great tunes and unswerving enthusiasm for giving airplay to plenty of new bands and solo artistes; it is quite unbelievable how much new music he's introduced me to from his studio within Salford's MediaCity.

Of course, he also plays scores of terrific tracks from days gone by and treasured BBC archive sessions.

Marc has immaculate musical taste. As well as a huge David Bowie fan he latterly discovered The Groundhogs.

Another very good reason to tune in is when he's joined by journalist Rob Hughes for the hugely entertaining Parallel Universe spot on Thursdays, from 8.30pm.

Anyway, tomorrow night (Tuesday) maestro Marc has Manchester band A Certain Ratio in session.

Now, this should be a real belter. The band released their first, Martin Hannett-produced single for Tony Wilson's Factory Records in 1979 and following the success of their second single, Shack Up, went on to be hailed universally as pioneers of what became known as punk funk.

Although, with the likes of Joy Division, then New Order and Durutti Column who became centre stage in Manchester's musical landscape, ACR did slip a little under the radar.

A superbly stirring, danceable mix of funk, jazz, electronics, and deftly created shoe shuffling beats enhanced with brass, A Certain Ratio more or less followed their own musical compass. ACR live is Jez Kerr, Donald Johnson, Martin Moscrop, Denise Johnson, Tony Quigley and recent addition on keyboards, Matt Steele. They have two new tracks, Make It Happen and Dirty Boy, recorded in the band's home city to be released with a new compilation, acr:set.

Not to be missed. By the way, White Denim feature on tonight's show.
