Let's start with some basic "purple notions". The stack bar-plot below shows which member of Deep Purple has been in a specific line-up, from the earliest Mark I to the current Mark VIII. All the graphs in this page are interactive, so you can select which member you want to obscure from the legend.
From Mark I to Mark VIII
This other plot is based on the classic Mark I - Mark VIII timeline you can find on all the best well-known Deep Purple fan-sites. The members' names on the left side can be selected, as in the previous graph, in order to customize the visualization. Each line-up is also marked with the years in which they have been active.
In order to be more accurate, the barplot below shows all the Deep Purple members for each related instrument. The members' names on the left side can be selected, as in the previous graph, in order to customize the visualization.
Over the years, several musicians shared the stage together with Deep Purple on the occasion of some special events, tour legs, or just for dealing with unforeseen circumstances affecting some members of the band. For example, many US tours in the Seventies have seen members of the band dealing with hepatitis, so proper substitutes were called to jump on stage if the shows couldn't be postponed or canceled. Other formations reported here are based on studio auditions, such as the ones held after Ian Gillan's second departure from the band in 1989.
Most influential artists in the Deep Purple family
In Graph Teory, the importance of a single node can be described by measuring its centrality inside the network. Many algorithms can be executed for this purpose, and, amongst these, Eigenvector Centrality can be described as the dominant eigenvector of the adjacency matrix used for building the graph itself. In order to quantify a node's influence, all centrality scores are assigned to the other nodes, by taking into account the connections between the high-scoring vertices. These connections contribute more to the score of a specific node than equal connections to low-scoring ones. A high eigenvector centrality means that a node is connected to many nodes, who themselves have some high scores. Hence, the number and importance of neighbors can be used to quantify each node's influence. Here are the 25 most influencial artists from the original Deep Purple network.
Artists’ PageRank scores
Google's PageRank is a variant of Eigenvector Centrality, and it measures the global influence of a specific node, by including its indirect influences. This algorithm has been used not only to detect artists who are significant in their own way, but also those who interact with more influential musicians. PageRank scores are expressed as percentages (a logarithmic scale is used by Google). For example, Joe Lynn Turner (0,68% score and 45 links) has a higher PageRank than Roger Glover (0,57% score and 63 links), even though there are more links to the latter one. This happens because the fewer links to Joe Lynn Turner come from more relevant artists than the ones to which Roger Glover is connected, and those connections are considered of higher value in this context. In fact, Roger Glover's links are mainly inside the Deep Purple line-ups connections (which belong to the same band), while Joe Lynn Turner's collaborations vary between multiple different projects.
Bands’ PageRank scores
The same criterion described above can be also applied for the bands. Festival events play, off course, a major role in this ranking, but also bands such as Whitesnake, Blackmore's Night and the Michael Schenker Group seem to be relevant given their numoerous line-ups, which include some of the most influential musicians from the original network. You can zoom inside the graph in order to see all the listed bands with the highest PageRank scores.
Deep Purple Members’ Universes
The following graphs are interactive too, so you can touch or click on a single "planet" to see who the main neighbors are inside each artist's universe outside Deep Purple. The bubble chart below shows the main families detected in the global network for Jon Lord. As said here, only the main collaborations have been kept in order to offer a better representation of the most significant relationships between each DP member and other bands or projects. Jon Lord played Hammond Organ and keyboards with several bands beside Deep Purple, ranging from his earliest professional band The Artwoods to the hard blues line-ups of Whitesnake and Bob Diasley's Hoochie Coochie Men. He also released numerous solo albums as classic composer and performer, such as Sarabande (1976), Beyond The Notes (2004), The Durham Concerto (2007) and the studio version of Deep Purple's Concerto For Group & Orchestra (2012).
